Yay! Harrison and Jesse Wells return! I wasn't entirely sure they would be coming back because their scene at the end of Season 2 played, looked and felt like it was their swan song. Props to great editing on that. I liked Harrison's new catchphrase "Not". It's a cheap life for sure, but it did the trick. 3 things are at play here. A new character called Magenta, who can levitate things. Not sure if she is going to be a recurring character though. Her powers really don't offer up much to keep her around. Jesse returns as a Speedster. We even get a glimpse of her new costume....albeit in a box. Can't wait till next week to see her don the new threads. As for Wally, it's clear what they are setting up. A man hellbent on getting his own set of powers will of course seek out Alchemy and make a deal with the devil. I hope they do it soon so that Barry and the rest of the gang will have ample opportunities to take on "Kid Flash", especially if he is evil.
