Part 2 - S1.E2

Aware of the fact that Gabi is spying on her, Sierra dresses a walker up in her Hazmat suit and uses it as a distraction to ambush Gabi. Sierra wants to know why Gabi is following her. Gabi admits to following Sierra and it was because Sierra could kill the infected and she (Gabi) could not. Sierra then uses Gabi as a shield to take down the infected in the Hazmat suit. Sierra begins to walk away, but Gabi pleads with her not to go. Sierra enquires as to how Gabi got her limp, and Gabi admits to twisting her ankle 'on the road.'
