Can you feel the love?

Addison's brother might be all better, but Addison is still pulling double duty (here and on Private Practice) again tonight. That pregnant woman with the brain aneurysm (what a way to bring Addison and Derek together again!) has a complication that'll take another episode - and more fireworks - to resolve. Speaking of fireworks: How about Derek punching Mark? And just so you know that this an extra-special episode, Faye Dunaway guest stars as a renowned surgeon - who screws up.
* Bones (8 pm/ET Fox)
It's doubtful anyone would ever call Booth a slacker, but after spending the last few weeks being temporarily blinded while kidnapped and suffering a broken hand and concussion playing ice hockey, the guy deserves a break, right?
