If you talk to William Thorpe and his wife, Keldorn will like stay for until you guys save Imoen right? Is he REALLY gonna go after that and never come back or will he touched by our lil story and stay?

Probably stay.

Oh no... what if he leaves?

Get Korgan instead?

I'd love to, but I have Aerie and they hate each other right?

Yeah, that's true. Regardless, my guess is he'll just stay along, so don't sweat it.

If you let him see his wife for a while so they can work it out he'll go for a day or two, but after a while you can go back, recruit him again and he'll stick around till the end.

However, as he leaves his wife jumps off the Firecam roof screaming "You homewreaker Bahamut!"

Or is that just your conscience that screams it?

So I choose that Keldorn be gone for a day and come back afterward, he will hang with me forever? Yeah!
