But Axel manages to actually hurt Ralph and damage his suit before Cisco vibes in and saves him. Back at Star Labs, they try to figure out how to get Ralph protected against Axel's acid.
At the prison, Barry goes to talk to Big Sir to thank him for the help. The reason he helped Barry was that Henry helped Big Sir when he was in jail. Elsewhere, the Walkers continue to plan their next dangerous trick.
