Coulson obligingly holds his hand out. AL runs her fingers over it and he activates (or deactivates?) something to allow them to see a trail of little yellow glowing lights that follow the touch trail and then disappear. He then presses on the wrist and a few yellow electrical lines appear. The jukebox and anything else electronic suddenly play nothing but white noise. He only lets it stay like that for a few seconds before returning things to normal.

He then smiles at Marty. "We're SHIELD. We have wifi everywhere."
