Just watched Lanterns episode 7. There was a scene where somebody went through basically a portable hole. When they got to the other side, they just walked away from it.

They'd just gotten done showing that the hole could be picked up, shoved into a backpack, and moved. So, the entire time I was like "pick up the hole! pick up the other side of the hole! what are you doing!? don't just leave that there" Maybe I've played too many video games
