I lean towards saving that sort of thing for TOB when Imoen is definitely feeling much better. So... don't hold your breath.
oh come on...at least a comment at spellhold about her "Player" brother if you have aerie, jaheira and Nalia in the same party..
Imoen: Oh Ao...you not only date this "Nalia" chick, but you keep your discards around? Bro, you make me sick...
Aerie and Jaheira: It's not like that!
Nalia: Finally! I like you Imoen.
PC: Am I allowed to say something in my defense?
Nalia, Imoen, Aerie and Jaheira: NO!
PC: This is hell, isn't it?
Jan: Not hardly, I still have my turnip stash. By the way, my boy, have I ever mentioned how I ended up in Hell once? There I was, laying down a pentagram of turnip skins, when all of a sudden...
PC: Shut up Jan!
Imoen: This is the hero of Baldur's gate?
PC: So not helping sis.
Nalia: He's actually good as long as he keeps his mouth shut.
Imoen: Dead on.
PC: So hating you all now.
