Sally Flymm: I'm here. But I can't speak. I can't act. I'm trapped.
Kyvir: Why would Enver do this to you?
Sally Flymm: He said he wanted to make us 'powerless'.
Sally Flymm: Still bitter after all these years. But we did what was best for him - for all of us.
Sally Flymm: We had debts. World-ending debts, trying to keep this cursed shop afloat. Dangerous lenders who said they'd bury us all if we didn't pay.
Sally Flymm: Then, a warlock offered us a pretty penny for Enver's service. He was a smart boy - too smart. It was give him up - and all of us live - or refuse, and die.
Sally Flymm: What choice did we have?
Kyvir: You had every choice. You sold your son to a warlock - that's unforgivable.
Sally Flymm: We got good coin for him. Closed our debts, and all of us kept our lives - Enver included.
Sally Flymm: You may disagree. Enver did. But we don't deserve this - this torment. You're the first person who's heard the real me in months.
Kyvir: You deserve what you got - and more.
Sally Flymm: Maybe. Maybe not. It's for the gods to judge me - not my wicked son. And not you.
Kyvir: Why would I help you after what you did to your own son?
Sally Flymm: My son! You've seen what he's like. Same now as when he was a boy. Hateful little wretch.
Sally Flymm: If you were me, you'd've sent him away too. Believe you me.
I wonder if Sally would've taken a different approach if she'd known she was talking to one of her horrible son's "nearest and dearest". Sure, Kyvir doesn't necessarily remember being Enver's friend ("""friend"""), but that's not the point! He's been going off of vibes since he woke up on the nautiloid anyway. Kyvir's current opinion of Gortash is basically "He called me his favourite <3" because Kyvir has Issues. Also I love how you can actually call him Enver instead of Gortash here, it's probably just because you're talking to his mother who's also calling him Enver but I've fully accepted the headcanon I've seen around that Durge was basically the only one allowed to call Gortash by his first name and so this is delightful to me.
Anyway, though. Imagine actually saying "Yeah, sure, we literally sold our son to this random warlock who happened to come through in order to pay off our debts and have been insisting we didn't do anything wrong ever since, but why would our son be bitter enough to want to punish us for it after all these years?" and expecting people to side with you just because your son also sucks as a person. Gortash is generally horrible but in this he is fully justified! Yes, absolutely, tadpole your shitty parents and dance them around like puppets who just talk about how great you are! A well-deserved tadpoling! But I do feel for Gortash here. Like... he's a shitty person trying to take over the world and he has to be stopped, but also you do feel bad for the child who got sold to a passing warlock by his own parents, who then insisted that it was right to do that. BG3 has so many characters who've been through absolute hell and then went on to do terrible things, the themes of the cycle of abuse are very very good.
