I have not finished my very first playthrough yet, but I am very close to the end. I have watched a lot of videos online though about the different endings. Wyll is the only companion whom I really love. I am a man who is quite into an old-fashioned gentleman with a good heart. To me, his story and Karlach's story are both good because they are the only stories where we face options that actually come with a huge sacrifice and struggle (I know Shadowheart has to face such a choice at the very end of one of her paths, but that is at the very end and is not that much of a struggle as what Wyll and Karlach have to face). This is especially true with Wyll since he did not commit any crime either on purpose or forced when the first choice is presented. Being forced to commit a crime can still be seen as a crime unless the person was totally not in control of the body or mind. However, both stories feel like there is something missing. I am not into setting up the two for romance because I love Wyll, and Wyll is mine. Lol. I do not play female characters in any games, and I do not want to miss Theo's beautiful voice when playing as origin Wyll. This post is mainly focused on Wyll, not Karlach, but she cannot be completely avoided.

Ending options:
I know a lot of players praise the ending where Wyll and Karlach and even Tav go to Avernus together while Avernus giving them a "warm" welcome. I actually hate this ending a lot. Yes, we have defeated the Absolute cultist and saved the world, but that does not necessarily mean that the 2 o 3 of us can withstand the entire 9 hells or just Avernus. I don't know how this can logically work out. They may survive for 6 months or slightly longer, but for the rest of their lives? It just does not make any sense even if it is just for a few years. Is Avernus such a lame or a welcoming place? I hope the game will give us an option to just allow Karlach to live with Hope in the new house of Hope after we have killed Raphael and saved Hope. If Hope can stay in Avernus, then I do not see why Karlach cannot. (Really, I have been wondering why we leave Hope there alone.) Wyll is no longer needed in this scenario, and it should make it less painful for us to keep Wyll with different ending options. I really don't like the fact that Wyll and Karlach's stories are so much connected. It feels guilty to kill Karlach or let her die, but at the same time, I love Wyll and want him to finally live a happy life. For anyone who has the ending option to go to Avernus, going to Avernus is always the worst scenario in my opinion. Since when going to hell is a nice or even an Ok thing???

I guess we do not want every companion's story or ending to be too similar or follow the same pattern. However, in a game where you need to choose only one character to romance with in most cases (this is good, not complaining), each one of them should have a better ending. This just does not apply to Karlach. I guess it is Okay to have one character with only sad endings, but then Wyll is kinda dragged into the situation. Yes, I can get him to become a duke living in the city, which is against his nature btw, but then I will end up in the loop of asking "what about Karlach?"

Romance:
Wyll's romance is not bad at all. I enjoy the slow but romantic process. The dancing scene is beautiful. I kinda hope that scene can last a bit longer. Lol. Some people may hate it though. What I want to say here is that being helplessly romantic does not mean no sex scene at all. Lol. Shouldn't the patient players be rewarded at the end? Give us a wedding scene and a sexy night afterwards. Wyll has significantly less content than other companions do. Make it up at the end. It won't break the character. The proposal scene in Act 3 feels weird to me because it switches back to the camp too soon.... It feels like nothing really happened except some kisses after they get down to their knees. Make it slightly longer after everything goes dark and let there be some noise. Lol. Alternatively, the camera can slowly move to a direction where we cannot see Tav and Wyll but the beautiful night, and then let it stay there for just a few seconds before everything goes dark. We can watch the tree or the stars while our imagination goes wild. Lol

If Wyll's father is dead under any circumstances, Wyll will break up with the player's character. This only makes sense if his father is killed by Mizora during the rescue mission. If Duke Ravengard is killed under other circumstances, this should not trigger because it does not make any logical sense when Wyll says that pulling him closer will get the player's character hurt. For example, if the party decides to work with Gortash and eventually let the brain kill Gortash (Duke Ravengard will die in this case, I believe), this breakup should not trigger. It would make no sense if it still triggers. Also, give us the option to be able to save the relationship either at the scene or during the party in 6 months after things have cooled down.

If Tav turned into a mindflayer and wants to commit suicide at the end of the game, the love should do something or at least have a stronger reaction. This is missing currently in the game, and it feels so wrong. This is not an issue unique to Wyll, I believe, but it feels even more wrong when he is the love. Romanced companions who should definitely try to stop Tav during the scene if they are in the party: Wyll regardless of status of companion questline, Shadowheart if she is no longer on the path of darkness and loss, Gale (you convinced me that I should live, and now you want to kill yourself?), Karlach(fine, soilder! I really did not plan to go back to Avernus, but how about you spare yourself and come with me, or you'd rather we both die here?), Minthara(what are you doing, my beautiful and sexy maniac!), and Halsin.
Suggestions:
During this scene, once Wyll realizes what Tav is about to do, he hugs Tav from behind putting both his hands/arms between the dagger and Tav's body.
Wyll: "We are not done writing our story yet. We just barely started. You can't quit now! I know exactly what is on your mind. I can assure you that we will face whatever comes next together, and we WILL make it work! Our story does not need to end now! Please! If you must do this, then let your blade pierce through my heart as well!"
Tav: (I use Tav here, but these can apply to Dark Urge as well)
O1. You can almost feel Wyll's heartbeat. Something starts to melt deep inside you because of the warmth coming from Wyll's body, or perhaps from his love. Your hands can no longer hold the dagger, so it drops to the ground.
O2. "I am sorry, my love. My existence will pose a huge danger to others and to you. I can't let that happen."
If O1 is chosen, Tav will turn around and hug Wyll with the following options:
1. "I am so sorry. I never wanted to leave you."
2. "Your love gives me strength. I am lucky to have you."
3. Say nothing. Just hold Wyll tight.
No matter which option is selected, Wyll looks at Tav with a warm and loving smile without saying anything. Narrator: "If there is anything that can get rid of the worries and concerns in your mind while giving you courage, it must be the love from Wyll." Other companions will feel released. The game continues to the next event or scene.
If O2 is chosen, Wyll: "We will find out a way. I already have a plan. We can discuss about it later. We just saved the Sword Coast from the biggest threat that it has ever seen. Together, we are strong, and we can overcome anything."
Tav:
1. (Strength Check) Try to get out of Wyll's arms and push him away. You must finish yourself. This is the only right way to go. (Skill enhancement from other companions cannot be used here. If rolled higher than Wyll's strength, Tav pushes Wyll away, and the suicide is done. Wyll kneels down near Tav's dead body. Narrator: "Wyll is so sad that you are gone, and that he was not strong enough to stop you." If failed the check, Tav has no choice but to drop the dagger.)
2. Use your illithid power to teleport out of Wyll's arms and tell him to live a happy life and that he deserves someone better. (if selected, Tav teleports away from Wyll but only by a short distance, and then the suicide is done. Wyll kneels down near Tav's dead body. Narrator: "Wyll's heart is filled with great sadness that is beyond description. He is trying all he can to hold his tears." Wyll: "You are such a fool! How can I be happy when you are gone? There is no one better than you!")
3. Ignore Wyll. Push the blade into your body. The dagger is not long enough to hurt Wyll. Others will help Wyll even if he gets injured. (The suicide will be successful. Wyll tries to hold and stop the sharp blade with his bare hands, but he failed. Wyll then kneels down near Tav's dead body while his hands are bleeding. Narrator: "Wyll is so sad that you are gone, and that he was not strong enough to stop you.")
If Tav tried to commit suicide but is saved, Duke Wyll will still tell Tav later that he wants Tav to stay in the undercity to be safe, but he will always try to be with Tav at night as long as he is in the city while Blade Wyll will try to spend time with Tav in undercity for as long and frequently as possible. If there was no suicide attempt, the epilogue remains the same with what it is currently in the game.
I guess Karlach's scene will always trigger before illithid Tav's suicide scene. If Wyll left with Karlach, then he is not there to stop the suicide.

My hope is not very high given that Larian is moving away. I guess I can always run these scenarios through my own head and pretend that everything went my way. Lol
