Compression of air as The Flash speeds should heat air in front of him, not in his back.
When Dr. Stein is explaining the time travel calculations, he says they will "inject a hydrogen proton into the particle accelerator." Protons are the same, regardless of the element they come from. A hydrogen proton is the same as an oxygen proton or an iron proton or a plutonium proton. Elements are differentiated (partially) by the number of protons they have. Hydrogen has 1, oxygen had 8, etc. The subatomic particles are the same, so the phrase "hydrogen proton" is somewhat meaningless; however, In Particle Physics, hydrogen atoms are delivered in "packets" into the first stage of the accelerator (Linear Accelerator). These hydrogen atoms can only be used after their electrons are stripped away, leaving hydrogen protons. This is why they are known as hydrogen protons, and not simply protons.
Reverse-Flash tells Barry: "Just so we're clear, after I kill you, I'm going to kill them. And then I'm going to kill your father. I always win, Flash."
That would have included killing Eddie Thawne -- his own ancestor.
Unless he didn't want to give anyone ideas.
