Barry Allen: What happened to Grodd?
Caitlin Snow: We don't know. After the Particle Accelerator exploded, I went down to check on him, and his cage was empty.
Joe West: So he could have been affected by the same energy that hit Barry?
Cisco Ramon: When the dark matter hit Grodd, all the drugs and serums that Eiling injected him with could've activated. Maybe the Accelerator explosion created a meta-gorilla. I think we know what happens when a super-intelligent ape who's pissed off at humans escapes captivity.
Caitlin Snow: Cisco's right about the first part.
