If the writers don't stop having the characters from both Arrow and The Flash from popping up on one another's series, I'm gonna be p*ssed once they do because I will have become accustomed to it. I wasn't expecing any cameos this week and it was a nice surprise because it wasn't an "event" as it was last week. It just seemed more like "hey, we are heading to Starling City" to investigate the scene of where Dr. Wells and Tess had their accident 15 years ago".  So, Cisco was able to confirm that the body he found was indeed the real Dr. Wells. If that wasn't proof they have been dealing with a fake Dr. Wells, having them find the hidden room that stores the Reverse-Flash suit is all the proof they need now. The cherry on top was having Barry, Cisco and Caitlin seeing the newspaper's front page proclaiming the disappearance of The Flash in the future. Can't wait to see what happens next. My guess is that they will keep the knowledge of finding the room to themselves as they investigate the matter more and will play along with Dr. Wells that everything is fine.
