Speaking of Gale... when he's encouraged to retrieve the crown and Tav is with AA, I find it interesting how at the end of the game
he still seems to have feelings for Tav (if you sorta or fully romanced him but then rejected him) and even tells you that if you ever felt differently, then there would be a place in the heavens for you with him. Then in the epilogue, he is the only one who acknowledges that you're a vampire and tells you that you both have eternity to catch up with each other. He also implies that you might be able to ascend one day if you're ambitious enough. To me it seems like he's still thinking about Tav and maybe one day he could even offer to whisk them away to Elysium if they spent more time together. Rather funny that he's cheeky enough to say such things with Astarion nearby, likely listening in with his heightened senses. And then Astarion says he almost wishes that someone would get in his and your way to have a fun challenge. Like... didn't just Gale make ambiguous suggestions, darling? I also heard that in dev notes it is said that AA is jealous of Gale reaching godhood. Looks like a potential for angst and drama, with Tav also having a way to escape from Astarion if they're being roleplayed as trapped in the relationship.

Another thing, when we kill Cazador without Astarion in the party, and when he tries to dump Tav for doing it, he cannot actually do it (like Tav cannot leave AA). The romance also gets very buggy, especially at the end of the game. Larian please look into it.
