We have our first peek at the upcoming episode of Supergirl that guest-stars Grant Gustin as The Flash. Gustin took to social media to celebrate the first day of shooting for the epi. Really, how cool is this? I can't wait to see how this crossover story unfolds.

The Supergirl / Flash crossover airs Monday, March 28.
