"(S08E18) Since I have no idea whether this is truly the end for Scrubs or not, I hedged my bets on the season vs. series finale label. I will say this, though: If this is indeed the end for the folks at Sacred Heart, they couldn't have gone out any better than they did tonight.
Tonight's finale hit on all the same themes that have carried the show for eight years: people grow and change, but life at the hospital just keeps going. Someone leaves, someone dies, someone makes a life-changing decision, and life keeps going. "It's just a day," as Cox almost-convincingly said during one of J.D.'s attempts at getting an emotional goodbye from his mentor. He's right. And as Sacred Heart didn't make such a big deal out of J.D.'s departure, neither did the show. He didn't even turn to look back at the ICU as he turned the lights off. Well, he did, but I'll talk about that after the jump..."
