Wells, Caitlin and others in “Unfinished Business”

Wells

Before I left Earth-2, I worked on a serum to dampen Zoom's speed. All we would need is for Ramon for a weapon to deliver it.

Caitlin

Oh, great, that could be this year's cold gun. Maybe another criminal can get it, and then we would have Sergeant Slow.

Cisco

I would never let that happen. Sergeant Slow is a terrible name.
