I knew you were coming before you ever stepped through the breach. I know all kinds of things that have been going on in your world. Tut tut, Dr. Snow. Stealing DNA samples to run tests. Cooking up experimental speed drugs in secret. You do have a little bit of a bad streak, don't you?

[ Reverb glances at Killer Frost then, to make it clear the comparison he is making. The examples were carefully chosen. Even Vibe doesn't know about either of those things. It is the quickest way to make it clear he knows her secrets. And, to his delight, transitions so meaningfully to his next taunt. ]

[ He tilts his chin upwards, proud, voice growing louder and boastful as he says: ] His obsession with proving he can run quicker than all the other little speedsters in all the other little universes has grown... tedious.
