He was on a heavy dangerous mission,things weren't easy from the start but he managed to get out of deadly situations. Yet he didn't expect turning back from his evacuation point just to save you. You were there with a team, last survivor but infected with Las Plagas.He removed it from himself and Ashley so he lets her stay in a safe zone before going back to you

You heard him calling in the distance,a second later he was in front of you "I'm gonna remove it from you. Hold on"
