Warning: Spoilers ahead.
I don'tdidn't actually get what happened in issue #3 of The Flash(New 52),the flash in the new 52's in the part where he's over analyzing the situation and he just freezesfroze, letting the bullet hit him in the head.
In issue #4 he's still alive, explaining that his instincts kicked in, but what does this mean?
Did
Did he vibrate unconsciously, so the bullet went through him? Where did the blood come from then? Why didn't the clones check if he was really dead?
I re-read it a few times and couldn't find how to answer those questions without making something up.
Note: I'm not that familiar with The Flash in general and his history (in other older comics), so perhaps there's a canonical answer I don't know.
