communion tree (slight spoilers)

[Kheros]

So I go and rescue 3 dwarves and 3 elves around the gem mine map. Problem is the last elf is the one right before the tree and he is stuck in a dialog mode where he will ask me a question and then pop right out of dialogue. I cannot get him to enter the tree with his companions...

anyone know how to do it?

ok...for those who are stuck at this part too, its all the gith's fault....she can be taken out of the party but the conversation trigger NEEDS her...

very annoying.
