Yeah, the Sam part bugged me, too. I think she was one of the people who needed more screentime and development than she got when she first came in. Though, the baby storyline was originally supposed to be hers, and then they switched it to Abby, so I think they didn't know what to do with her for a while after that.
And I loved the montage with the voices, too. And the slideshow at his going away party. Only thing I wish they'd included was one of him and Deb. The Jinter shipper in me wanted it, but they were also very close friends as well as colleagues. He was the one she called when she went into labor and he was there to support her when she gave up her baby, so that kind of annoyed me a little. But it was still a great episode.
