I noticed during the San Jose game, that after Chimera's goal, he skated immediately to Peca, who gave him the assist, and they hugged very enthusiastically. FSN cuts away, and when they come back, Chimera emerges from another embrace, locks eyes with Peca, shoves him really hard, and turns and skates away really fast and looking angry.
I can't tell if it is just a "I'm fired up" look or if Peca insulted his mother or something. It looks to me like Chimmer said "That's what I'm talking about!" or similar, but I'm not sure.

Tell me what you think, or if you've heard anything about the incident, or if you've heard about something from their past.
I really think he was just fired up... but, man, watch it a couple of times, and wow... sure looks like there is something there.
