marcellas seems to want the other side to take out howie/james to force kaysar/janelle to align with him and erika. the thing is james is a huge threat, which could help janelle, because somebody might want him gone more then her. also he is great at the competitions, where howie at least isn't.
would she keep james, because he is safer to stay with, because he is good at competitions. he always talks about how he should have saved rachel. also, she could possibly beat him at the end, kaysar she couldn't.
you have to give kaysar though some credit for an hoh win, and all that time in the pressure cooker.
