Wally hears a voice, which makes him look over from working on a car engine. At first, it's not a big deal, he's met super-heroes before even in his civilian identity. But it's the way this man looks at Wally that is so attention grabbing. The smile, he'd know it anywhere. Then the statement about being the fastest man alive followed by a wink. He knows...
Wally suspects on who this man might be, but half his face is covered in a mask. "Excuse me guys, I have...a phone call. Be back in a jiff." He jogs, at regular speed, into the bathroom. Faster than the human eye can see, he speeds out as Flash Lightning.
There he is, up ahead. Flash Lightning thinks to himself, running after him. He easily speeds up to try and pass Velocity before trying to block his path by stopping directly in front of him, putting on the brakes by bending his knees and digging into the concrete.
Should Velocity slow down and stop, Flash Lightning stands to his full height of 6'0" tall. "Nice outfit." Wally says, glancing him over once, then looks at the man's face, "How do you know me?"
