That’s right, it looks like The Flash season 1 villain, Peek-a-Boo, will be returning for the season 4 premiere.
Actress Britne Oldford will once again make her presence known in Central City as Shawna “Peek-a-Boo” Baez, and she’ll likely be causing problems for Team Flash with her powers of teleportation.
The first time The Flash introduced Peek-a-Boo was in Season 1 Episode 12, titled “Crazy For You.” After Barry successfully halted her powers of teleportation by taking out all the lights in the area they were fighting in, Shawna Baez was imprisoned within the power-muting pipeline with all the other villains. Baez was freed in Episode 22 when Leonard and Lisa Snart attacked the truck hauling the meta-villains away from S.T.A.R. Labs to another facility. It’s unclear what Baez has been up to in the two seasons and how she’s changed since we last saw her, but something big is obviously bringing her back.
Peek-a-Boo has had adventures outside of the traditional storyline in The Flash, as she was briefly highlighted in the official web series The Chronicles Of Cisco. Peek-a-Boo battled a pre-meta Cisco in a dream and shot him, although it didn’t exactly work, as Cisco inadvertently invented a bulletproof material using orange soda. Cisco awoke from the nightmare and found a bullet on the ground which made him question whether the whole exchange was really a dream, which would definitely be an interesting twist to her character should The Flash team address that. It’s highly doubtful, but still worth noting all the same, especially if she shows up in someone else’s subconscious.
The Flash returns to The CW for Season 4 on Tuesday, Oct. 10, at 8pm EST.
