Steve tried not to hover around like a worrying mother, but as more people arrived and those that were there traveled to other places it left him a little highly strung. Luckily most of the people who'd ended up there so far seemed able to take care of themselves, but some were young, some were his son from another universe and it really didn't sit all that well with him. So Steve did what he did best in times of great stress.
He ran.
It was a good way to quiet his thoughts, maybe to keep an eye on things and check the perimeter, but mostly he put one foot in front of the other. He was on his third lap through the square when he spotted the other man, hand on his gun and looking a little lost. Steve slowed, running a hand through his hair as he approached head on with his hand held up in greeting.
"Hey," he said, slightly breathless. "I'd say don't panic, but a little panic is probably called for."
