OK so i let him go spend time with his family, then he came back and was all mad that his wife was cheating with him. so we went to see the guy in the inn in waukeen's promenade. After you go back to his house, there are only 3 option to pick from: Let him stay home forever, let him have a day and then have him back until you get imoen, or just keep him til you get imoen. Is there no way to keep him for the rest of the game?

I always chose
"let him stay a day"

You get exp points and collect him for the rest of BG in a day
His wife doesnt mind etc
seems ok to me

I always let him go home to stay. There ar other tanks available! Though Keldorn is the best.... Mazzy is pretty good. Thought about using her? Her bow skill is VERY useful!
