I'm playing as Nate (for the completionist in me) and went to save Ivo and Wilbur from the troll. When Nate casts the fishing line guess who does it?

IVO stands up, walks to where Nate is standing and casts the line!

So now Ivo and Nate are occupying the same space. When Nate eventually moves Ivo remains. Very funny while the rest of the scene unfolds with Nate now talking to thin air.
