If Bonnie does die, I can see Archie trying to comfort Alex and assuming it's her first death, and Alex in her grief revealing a little bit more to him about her life (re:Max and the other deaths). She also left her broom out in the open, has Archie ever seen it before? With the way he's been more inquisitive lately, I can see him being let in the loop a little bit more sometime soon.

So this is real life...
