Fortnite Quickdraw -- Lucky Deagle Shot

I was cruising around the frozen lake gathering loot, thinking I had the whole place to my self. I went into this house to look around, and no sooner did I hear a gun cock then I had somebody shotgunning me in the back from point blank range. I whipped around and let off an impulsive deagle shot and somehow got them right in the dome. I don't even know how that person got there, but-- phew-- I got lucky as hell on this one.
