This Guy Was Really Annoying

Donnie stared woodenly at the guy who had suddenly appeared. How should he put it? His first impression of this silver-haired guy was... pretty damn annoying... "Who the fuck are you?" Donnie asked, despite already knowing. As far as he knew, there were only two speedsters around right now. One was Reverse-Flash, still lurking in that backwater called Central City and keeping a low profile. That guy was painstakingly trying to create the real Flash, Barry Allen, ahead of schedule so he could return to his own era.
