"Wait, wait, wait."

Wally's eyes grew wider beneath his cowl.

"Green Arrow is here?"

A surge of lightning propelled Kid Flash forward, feet skidding into the raised edge of the building as he peered over into the dark street below. Thoughts flashed and crashed through his mind. Too many thoughts, and too many thoughts about those thoughts. That was the problem with being a speedster: even thinking at the speed of light took time, if you had the sort of brain that was compelled to consider every implication and permutation. Like, Roy being in town for example. Why hadn't he called? Okay so sure, it had been a while since they'd hung out and whatever, but they'd fought crime together. Saved the world, hyperbolically speaking. It wasn't like Roy didn't know that Wally was here in Gotham now: hell, Roy had liked his Superfriends status when Wally updated it, so Roy knew he was here. Had he just forgotten? Was that the kind of detail that slipped a person's mind? Or had it been deliberate, willful, the older sidekick making a choice not to draw attention to his presence? To avoid being burdened with the younger and infinitely less cool speedster who had isolised him back in the day? And then what about the other stuff? If there was a new Speedy, or Red Arrow, or whatever, what did that mean for the old Speedy? Did he still rock around in the same outfit, the two of them all matchy-matchy and cool? Or had stuff changed when he'd left for college? Was he someone else now? Something else? What about -

It was half-way through that string of thoughts when another fragmentary shard of Wally's attention stumbled across something as it slowly processed its way through the various visuals and images that had blurred past him a he ran, the data taking an eternity to process as if it was being downloaded from a space probe on the far side of the solar system.

"Oh no."

Wally felt something wrap around his chest, a tight icy grip as the blur of green resolved in his mind into sharper and sharper focus.

"Oh no."

Another burst of Speed Force carried him stumbling backwards, the shallow breaths of anxiety beginning to take hold in Wally's chest. Guilt drove itself through his heart like an arrowhead, a sensation he was surely going to experience first-hand before the night was out, because of what he, in the blurred oblivion of his speed, had done.

"I ran on the Arrowcar."

His wide eyes glanced at Red Arrow for the briefest moment, before abandoning her scarlet visage to stare in horror at the ground. He didn't deserve to look at anything cute and leather-clad, not after what he'd done. Wally's innards turned to ice. Did he damage it? Scratch it? Was it okay?

"G.A. is going to kill me."
