Did I cut myself on my own Pulse Blade??

What the hell damaged me? Completely inside the building, no line of sight to anywhere else, an entire thick wall between me and anything outside that could've been behind me. I pull out my Pulse Blade for quick sonar, and something hurt me. Somehow, something hit me from behind (lol) and damaged me, I have no idea what.

Either it's source spaghetti, or I'm the first TitanFall pilot to somehow nick their finger on their own Pulse Blade. Would be a funny rare chance scripted moment, like the "👌" hand motion with the Time Travel Device in the campaign, though I'm guessing it's the former.
