Ekko looks concerned, fussing with the edge of his gloves and scowling at the TV. He knows metahumans and he also knows how hard it can be to actually keep in check of powers, especially when they're new. This kid looks about as old as him and he's never seen him anywhere else before-- and nobody else has either.

Which means he probably has no clue about the Underground. He clenches his teeth and balls his hands into fists. "We have to find him. He probably doesn't have a clue what he's doing."
