Uzi was walking around outside, mostly just wanting to get away from people from a while, when she noticed something sticking out of the snow that she couldn't really make out.

So what did she do? What any logical person would do of course! Went over to the thing!

She grabbed the thing that was covered in snow and pretty much unrecognizable and started dragging it back to the bunker, specifically where her window was, and she pushed the thing inside before climbing into the window herself and closing it before laying the thing in her computer chair.
