The problem with that is some tournaments can last years - so if a BB wants (for whatever reason) to kick a certain player out, it is there fellowship and should have the right to do that.

Everything with that tournament continues with no issues. Next rounds will start just like they should. So I'm not sure what your question is about each player that is teamed up with should get a draw to make it even - the tournament will continue - no matter what the status is of the fellowship.

I'm also not sure about your example question - other then being listed for fellowship members only, tournaments have nothing else to do with fellowships - so a tournament will continue as normal no matter what the status is of the fellowship.
