I'm assuming that you modded your Merril? Because Anders is my only option. :(
And you don't bring Carver along because you like him, you bring him along for the party banter. Isabela absolutely loves teasing him, and it's
hilarious.
Or just read the dialogues. What's surprising is that he actually seems to like Merril. I would have figured the blood magic thing to be a huge turnoff for him.
My favorite dialogue is still Anders/Sebastian regarding his belt though.
Okay, Isabela/Sebastian is hilarious too.
Sebastian: Is this getting you any closer to your ship?
Isabela: Huh?
Sebastian: I just... don't understand why you're working with Hawke. You don't seem to care about anything we do.
Sebastian: What's keeping you here?
-If Hawke and Isabela have slept together:
Isabela: Mostly the sex. Hawke is an absolute tiger between the sheets. I mean all night, every night.
Isabela: Oh cute! You're blushing.
-If not:
Isabela: Mostly the Blooming Rose. I'm paid up through the end of the year. I'd hate not to use it.
Sebastian: The... brothel?
Isabela: What? Women can't go to brothels, too? You're just not using your imagination.
Isabela: Oh, look! Now you are. You're cute when you're blushing.
