This was easily one of the best episodes of this season. I mean, the reasons are obvious. One, they had the entire cast give one of their solid performances. Two, they tried to keep the fun level up by keeping the right amount of nostalgia stuff.
We see Elizabeth Banks was back to give JD a shock. She was apparently dating Shaun who happens to be Eliot's ex. JD's agony piles up when his kid shows a greater attachment to Shaun as opposed to him. I liked the fact that they made a serious concept into a fun filled one. As a parallel storyline, Turk starts stalking Cox for the Chief of Surgery post. We see Kelso giving his testimonial for Turk, which finally convinces Cox to give him the job. There was a brief nostalgic moment when Kelso leaves the hospital, but again, like I've mentioned before you are setting the stage for a fitting farewell.
