Love that Barry, Cisco and Caitlin finally discovered Dr. Wells is the Reserve Flash. Cisco geeking out was kind of funny especially him dropping another Back to the Future reference. I really do hope they update Barry's costume because the future version looks so much better. Surprised to learn that Barry created Gideon in the future and I thought it was cool Gideon nearly name dropped the Justice League. I'm hoping that Cisco remembering the alternate timeline has something to do with his powers from the comics. Interesting use of The Flash's powers during the fire rescue scene. Tom Cavanagh gives a great performance in this episode super creepy. Wasn't expecting him use Hannibal Bates like that but nice call back to last week. Iris finally knows Barry is The Flash. I'm really excited about Grodd next week.
