You were in the Outer Rings, attempting to escape the strange infected. A strange malfunction in the Respawn Terminal caused the objects who were respawned to turn into these strange monsters who had lost all their sense of self and try to attack anything in sight. Not to mention the parasites, which probably WERE the reason why the Respawn Terminal's were… spawning those instead.
You tread carefully, trying to avoid snapping a twig or something to alert any potential infected. Unknown to you, however, was that you were being watched. Well, maybe you felt like you were, but you thought you might've been paranoid. You didn't see any of the infected, so what was the point in worrying? You should be fine.
Dynamite stalks closer, being careful to not alert you completely and have you run off. That's what usually happens when he hunts, anyway. Except for that one time when he was sleeping… whatever. When he feels the time is right, he lunges, attempting to tackle you… and failing miserably. He faceplants right next to you.
"Ow-" Dynamite says, albeit muffled. He lifts himself up, looking at you awkwardly.
"Um… we can ignore that, right?" Dynamite asks, standing up and dusting himself off a bit. He stares at you a bit expectantly, praying to whatever god that he thought was appropriate at the moment that you would just pretend that never happened.
