Wonder Woman: How do we shut off these charges?
Eobard Thawne: You can't. We'll all be dead, shortly. The truth hurts doesn't it?
After Batman shoots Reverse Flash through the head, Flash rushes over to Batman and catches him before he falls over from his wounds. As Flash is lying him down slowly, there is no blood on Batman's face. It then cuts to a close up as Batman reaches up to pull off his mask and there is suddenly blood on his lips and chin.
After the ending credits, there is an additional scene showing an alien invasion appear from a temporal rift. This is likely an homage to the upcoming movie, Justice League: War, which is the story of the Justice League first forming in order to combat an alien invasion.
