Very true...the personalization, or over-personalization it seems at times, adds a much deeper element to the Foyet/Hotch dynamic. Both men have been invested in the other - in one way or another - for a good chunk of their lives (much like, if not even more than, Gideon and Frank were in previous seasons - I can't currently remember if Frank's first appearance on the show was the first in Gideon's career or not). That fact alone changes the inner monologue, and thus behavior, of both the victim and the attacker...and my guess/hope is it'll continue to do so throughout this season.
