I had yoshimo in my group when I went down to the asylum. He betrayed me. Does this happen if you don't have yoshimo in your group? If you do have another character in your group, does he/she betray you as well?
I would really like to keep yoshimo in my group cuz his snares are pimp.
There are much threads on this, but the simple answer is, no...sorta. There is no legitimate way to keep Yoshi, but there are some cheese methods. Check the threads. As for other betrayals, he's the only one I know of.
I know about all BG2 players have already finished the game at least once, but could you please not put such a thing in your subject? Also, put "SPOILER" in it when you ever post a thread like this again.
dafreak,
For future reference, could you please refrain from posting potential spoilers in your topic. It ruins part of the game for those of us who haven’t gotten that far yet.
