Labs after saving the day and giving an interview to a local news station.
We learn that Zoey is the Bonnie to OG Tricksters Clyde.
Ralph recklessly wades into danger, expecting an easy fight.
(Team Flashs befuddlement over what was going on with Ralph and the acid was particularly amusing.)
However, Ralph refuses to take the bait because hes scared of dying.
Barry refuses to go with Ralph, who stretches his way into his cell.
Ralph storms the Trick-familys hideout and manages to take out Axel by turning himself into a slingshot.
However, Zoey manages to flip the lever that releases the acid onto Caitlin and Cisco.
Imprisoned and under constant surveillance, Barry cant use his powers and feels useless because he cant help people.
Barry sneakily uses his powers to save his saviors life and gains a friend in the process.
Fingers crossed the show regains some of that momentum next week.
