Interestingly, Jesse L. Martin, who plays Joe West on the series, was also photographed on the same outdoor set Oldford was spotted. In the photos shared by the same Twitter user, Martin as Joe is seen wielding a firearm. Is Joe trying to catch Peek-a-Boo using that futuristic-looking weapon?

Oldford’s Peek-a-Boo, aka Shawna Baez, made her first “The Flash” appearance in Season 1, episode 12, where she broke her boyfriend, Clay Parker (Micah Parker), out of prison with her new metahuman power of teleportation. After freeing Clay from prison, Peek-a-Boo wanted to leave Central City with him right away, but Clay told her that he had to pay a debt to crime lord Marcus Stockheimer (Jerry Trimble) before he could leave.

Shawna and Clay met with Marcus to pay off the latter's debt, but when Marcus witnessed Shawna’s metahuman abilities, Marcus decided to keep the two around for a crime spree. When the couple raided an armored truck, The Flash (Grant Gustin) confronted them in a tunnel. The Scarlet Speedster destroyed the tunnel lights and the headlights of the couple’s getaway car, rendering Shawna unable to teleport. Clay managed to escape but Shawna was captured by the Flash and was imprisoned in S.T.A.R. Labs’ Pipeline.

Shawna made a reappearance in Season 1, episode 22, where the Reverse-Flash (Tom Cavanagh) freed her and other metahumans from the Pipeline. She nearly killed Caitlin (Danielle Panabaker) for imprisoning her but was knocked out by Iris (Candice Patton) and returned to her cell. She and other metahumans were then sedated and were moved out of S.T.A.R. Labs in a truck. However, Team Flash’s plan to transport the metahumans to another location became a disaster when siblings Leonard (Wentworth Miller) and Lisa Snart (Peyton List) sabotaged the truck. A battle ensued, but Shawna decided to take the opportunity to escape, teleporting away.
