As far as Blake 'fighting nothing', we still don't know the whole situation. For all we know, it could be a training thing, dream, or something else entirely

And in addition, I believe Monty confirmed some scenes in the trailer had different context than the appearance - such as the RubyXWeiss 'scene' possibly appeasing the shippers (lol)
