It wouldn't be Quantico if Alex was not running around during an episode, and this Sunday we will see her back on the run with another survivor due to terrorists taken over the building.

Tune in Sunday, October 16th at 10/9c to find out. In the meantime, get a sneak peek of the action in the clip below.
