It's a real shame that Bucky and Steve never thought of what the consequences would be for leaving Tony Stark in the bunker would bring upon them. They never noticed the slight shift of the air. They never noticed the 4 pairs of luminous demonic eyes following their exit. They never realized the killer intent that could of obliterated them where they stood if it were not for that one simple brokenly whispered, "D-D-Don't..."They didn't even seem to sense how close they were to meeting Death in her most simplest form when those 4 pairs of unearthly eyes landed on their Alpha. Therefor, when they got back into the good graces of HALF America's citizens, it was such a rude awakening when Team Captain America walked into the Avengers Facility and tore into Tony Stark, as if he were the prey and they the predator, did they notice something was off. But they were too late. It's like they say, "What happens in the dark, ALWAYS come to light."
