Colton roughly pulls Gabi and holds her by her face, repeating "Didn't I tell you to wait for me?" They hear Sierra getting up and making her way further down the tunnel. Colton calls out for her to wait and begins to follow her but falls due to his injury, but Gabi tells him to let her go. Colton says he can't, that he has to get to her before THEY do.
