Black Siren
- Black Siren: I met your little red friend tonight. Aren't you gonna ask me if I killed him?
- Hunter Zolomon: You didn't. You're good but not that good.
- Black Siren: And yet I seem to be the only one of your top lieutenants still standing.
- Hunter Zolomon: Like I said, you're good, so why don't you go knock down a few more buildings like I ordered.
- Black Siren: What's the point?
- Hunter Zolomon: The point is so that it seems random. That way The Flash and his merry band won't realize what I'm up to till it's too late.
- Black Siren: What are you up to?
- Hunter Zolomon: No good.
- [as Cisco and Caitlin impersonate Reverb and Killer Frost]
- Black Siren: You know, all doppelgängers, they're mirror images of themselves, but you two... you didn't know that, did you?
- Caitlin Snow: Reverb is left-handed...
- Cisco Ramon: Well, I just... I just happen to... catch it with my right... RUN!
