Fear the Walking Dead (2015): Passage: Part 9

The tripwire was activated and caused an explosion. Sierra and Gabi wake up with ringing ears, coughing, and covered in dirt. They call each other and Sierra tells Gabi to follow her voice a couple of times and tries to activate a flashlight. While Gabi is trying to get her bearings again and look for Sierra, a light is seen behind her. She is then grabbed by someone who is revealed to be Colton (who in fact recovered from his wound) holding a flashlight.
