I give it an A. Enjoyed the setup and the son's involvement to basically save himself. Seriously, Mac is always so damn panic stricken when Jo is visibly fine after stuff -- I never get that. Christine herself is fine -- the actress is okay (even if I can't get "Ever After" out of my head) and they had an okay vibe, but I personally hate that she's tied to his past with Claire. If she'd only known Mac, I'd be fine with that, but I really, really can't get behind the idea that his possibly happy future is tied to his past with Claire. It's a little too romance novel for me.
