After spending time trying to sort out my thoughts, I'm just going to ramble through things.

Mike is severely pissed off at Rasmus, feeling that Rasmus hiding outside and not aiding Mike after a Lightning Bolt was cast was an indication of Rasmus leaving an ally to die as long as he was safe.  Mike was fighting for his life and all he heard was Rasmus talking rather than actually helping.

There will obviously be an argument where Mike will be yelling at Rasmus.  I'm not sure if the rift can be mended at this point.  Rasmus will need to prove himself trustworthy in Mikes eyes and that could take awhile depending on what happens in game.  

I do see this putting strain on the rest of the party.  They're going to be caught between the two of them and trying to decide how to help as well, if I'm reading everyone correctly.
