I'm not really fond of the Giorgio/Lucia plot, Jackson Rathbone is overacting too much. What made this episode great was Adam Baldwin. I loved to finally see him together with his wife and kids, even if only in flashbacks sequences. I don't watch the show religiously so I don't remember if Chrstine is dead or still MIA. If she isn't dead, I really hope to see an actual reunion in 5th season! The Sardinia part wasn't really believable but the Italian lady did a good job in making it more believable. Best episode of 4th season so far!
