Planescape: morale?

Annah just left me in the middle of a dungeon after being pissed at fall from grace. Ive read somehwere that its about morale - but how do i raise morale after exhausting all dialogue options? I was nice to annah and didnt make fun of her - what can i do?

from here:

I think when I tried the "If she bothers you so much I'll make Grace leave" tactic, it only worked temporarily, and if it came time for her to do another banter, if she wasn't gone, she'd leave the party again. The only way I managed to get her to rejoin permanently was to basically get rough with her and say things along the lines of "Okay, fine, go back to fishing for corpses in the slums again". That shuts her up quick.

And that is the current hyped RPG of the forum? Looks like players get no clue on what to do and that the dialog subtlety is rather tiny.

I'll generate a riot but frankly I feel Eiger in Dragonfall is hugely better managed.
