An earlier scene was shot inside upstairs with Tom Cavanagh. Then as he left, those needed for the exterior scene arrived. Grant Gustin was in his Flash attire, and I I saw Patrick Sabongui on set as Captain Singh, but it was dark & he was far away, so I never got any good shots of him.
The scene is pretty cut & dry. People in an apartment/business tower evacuate as fire & police show up. Then, lastly, The Flash comes to the door & speeds away.
The Flash and Barry Allen/The Flash are up for this years May Madness tournament going on right now HERE
