"Helpless"
*Peekaboo's father, Tomas Baez, is dying as his donor organ has not taken well. And Hunter Zolomon asks Flash to take him back in time to change the sequence of events that led to his paralysis; Flash must refuse, because he knows that playing with time travel is incredibly dangerous. Tomas Baez dies, and Peekaboo turns herself in, feeling she has nothing left to live for. Flash feels like a failure, so Linda decides it's time they had a family meeting and told everyone about her pregnancy. And Hunter Zolomon decides to take matters into his own hands. He travels to the Flash Museum and attempts to activate the cosmic treadmill, instead causing a massive explosion. *Source: dcuguide.com
