the death of the BF is quite possible, but this should be the end of the BF storyline regardless, and probably the end of the Gideon/Saviorology storyline as well. Which would make sense since 6x20 is the Musical episode, and it might help for that episode to be outside of the existing storylines. and then 6x21 and 6x22 will be the season finale, and these typically have very little to do with the story lines established during the season (even if some event from the season is the trigger).
