Barry Allen and Nico
Nico wasn't someone Barry had interacted with while he'd been under the influence of the Mark. In fact, Nico wasn't sure they had ever talked at all when he saw Barry.
But he was here to have a good time, to enjoy the fireworks and the food. It was still daylight, so the light show hadn't started yet. Nico randomly decided to greet Barry as he walked near by.
"Are the corn dogs good? They can be iffy. Especially at an event like this."
