@TheCrowbar: I respect your interpretation, but i don't think most people would agree with you on it.I think most people would read that panel and think the same thing I did, I don't see this commentary anywhere else but with you on this forum.

Jason specifically says "Rescue might be overselling it," They needed firepower, Starfire brought it.
These are 38's firing if anyone was curious:
