That's true. Brady and Shawn could be buddies.
I think DAYS needs some friendships. I get it's harder to justify spending time on building friendships but .... it's lacking. And would go a long way towards character development.
It is odd BB/MM don't have any chemistry together. They seem to get along and like each other; which translates, but no chemistry.
Kristen was such a big part of the original Possession and it would be a way to tie in what was a seemingly pointless plot from a few years ago. Maybe Lani could be first to suspect something or Kristen needs to be part of the exorcism and 'redeems' herself. Again, Eric would be useful as well.
