The Flash will make an appearance in an upcoming episode of Supergirl, CBS announced today. Grant Gustin, who plays Barry Allen and his titular alter ego, will appear on a March 28 episode of CBS' series, but the network neglected to elaborate on further plot details.
The Flash airs on The CW, alongside other DC Comics series such as Arrow and Legends of Tomorrow. Supergirl is CBS' lone superhero-centric program, although the two shows — along with Arrow, which had a crossover with The Flash of its own in December — share executive producers.
We recap both The Flash and Supergirl weekly. Supergirl aired its latest episode Monday, while The Flash runs new episodes every Tuesday.
