1) I realize it's probably been done to death on other shows, but I wish they would've shown Derek looking for the ring he threw into the woods. It could've been dramatic and they just skipped it. There was a rumor that there would be three proposals. The first was at the breakfast table, where he basically just placed the ring in front of her with a somber look on his face. Sooo romantic. NOT! The second was right before Izzie's surgery, where he basically demands a confirmation so he could operate with confidence. No way, no how! The third, in the words of Goldilocks, was juuuuussssst right. He recounted their love story using x-rays of every patient they had together that marked an important moment in their relationship: their first surgery, the first time they were caught doing it, the first time he knew she would be an incredible surgeon, the first survivor of their clinical trial, etc. With a clean-shaven face, he told her that he wanted to spend the rest of his life with the woman who gave him strength...and she agreed.
2) Who was Owen choking? Yeah, I know it was Christina, but who did he think he was choking. The nightmare he had that led to him choking Christina was triggered by the ceiling fan, which resembles a helicopter (if you're crazy). So in what scenario do you go from a helicopter to choking someone? Was it an enemy or a fellow soldier? This has potential scandal written all over it. While I hope it was your run-of-the-mill, life-and-death situation, I'd prefer a better excuse for why he almost destroyed a budding relationship.
3) I appreciate that they treated Alex's decision to fertilize Izzie's harvested eggs with the proper weight. It's the logical thing to do, but it's also a huge step in a relationship.
4) I'm glad they gave George some screen time, but Callie's residual guilt for wanting Izzie dead when he cheated on her was ridiculous. Really? That's all you got?
