I thought it was kind of weak that Barry just stood there and let his mom die based on a subtle wave-off from his future self...would have been more dramatic if they'd done a COTEOF and Future Barry had actually held his past self back.
The question is, what has Future Barry learned that made him wave himself off, and how did he learn it?
