Wesker doesn’t typically get distracted. He doesn’t allow himself the luxury of a single moment of weakness, especially not during combat. So what a massive blow to the ego it is when his blade slips from his grasp, half-embedded in a zombie skull. Not even enough to end the thing yet, barely enough to slow it down. He’s pushed to the floor, a precarious situation if you hadn’t been there to shoot it. Wesker shoves it off and gets to his feet. You, of all people! He offers no thanks, naturally.
