I don't think that Astarion's big secret is that he's a vampire spawn, but rather WHY the Gur felt the need to beat him up in his own turf when he was alive and powerful.
Myzora is a feature, not a bug. Can't wait to get to know her better, she seems awesome based on her datamined lines. I like Wyll, but it's true that his voyeuristic eye is a bit of a romplock.
Gale is incredibly manipulative and very judgemental; he keeps throwing shade at "unnatural" things like "raising the undead", "corrupting hags", etc. when he keeps raising himself from the dead because he's literally corrupted with unnatural magic that could destroy the universe, far beyond the scope of any necromancer, vampire's or hag's magic. He looks in the mirror but only sees what he wants to see, while Wyll and Astarion have a clearer vision of who they are and what they've done.
Lae'zel is Bae and my Green Queen. Weirdly enough, she seems much more open to change than Shadowheart -- she's vows to help the party at the Githyanki crêche, and is quick to turn against her own people if they refuse to help her, re-evaluating their motives.
I like these romance routes, because each and every one of these characters are setting the PC up both for an extraordinary romance... or an exquisite heartbreak. For instance, take Astarion's personal quest, and assume that he succeeds.
- He could take Cazador's place as vampire patriarch -- in which case goodbye any positive characteristics, including "fun" and "pleasure" and "through lover" he will be all Evil. If your PC is Neutral or Good, that might be a deal breaker going forward, particularly given his moral flexibility regarding thinking slaves.
- He could kill Cazador, in which case he would revert to his elf-self, losing any vampiric powers and keeping the parasite. A bit of a bummer for a survival-obsessed character.
- He could imprison Cazador without kiling him and take his vengeance slowly, a risky prospect that would allow him to remain "the most powerful vampire SPAWN" in the realms as long as he kept the parasite. In which case, if he doesn't want to renounce to the perks of sunlight, entering houses without permission, etc... the PC would have to accept the risk of Astarion abusing the illithid powers or bind him with Omeluum's ring. "Wth this ring I bind you, till undeath does us apart."
You can already trace similar tales for Wyll and Gale.
Lae'zel's story seems to point at an eventual confrontation with Vla'akith, while Shadowheart's path is still covered in shadows, truly the most mysterious of all.
