I've been saying there is a real Jay Garrick but he won't be played by the same actor. And I thik the thing about Henry's mother's maiden name confirms that.
I think it's safe to say Wally and Jessie just became Speedsters.
I fond the ending really compelling, then the preview shows Barry will be there next week. I was hoping the show actually was going to spend awhile acting like Barry was really killed off.
