The flashbacks with Wells and Eobard were interesting, the gimmick Eobard used to steal Wells body was very similar toi the one in Fringe that was used for body-snatching.
I am now thinking this body switcheroo gimmick is how Eddie's sudden heel turn comes about, once the Wells identity is exposed he's going to need a new body to use that will still keep him close to Barry. Of course that might prove tricky given they are relatives.....
As for the Trickster's story, I absolutely loved it, just classic comic book goodness and Hamill left no piece of scenery unchewed lol, plus he got a neat little ESB homage in.
The whole tone of it reminded me of a STAS episode.
