On this blessed day of meeting new people and making life-long friendships, Mabel just so happened to be in the mess hall, halfway through her meal (which consisted of a tray full of little ice cream filled cups, and one only slightly gross vegan pizza with extra sauce). And of course, from her seat she saw the whole thing. Rebecca's fire and subsequent wall slam. Did that girl disappear for a second or two?? Mabel's not sure.

But, the whole thing does bring up a pretty nostalgic feeling. The kind she used to get whenever Dipper would go fleeing from a room to sulk somewhere. For a moment, she just frowns down at her tray. Until she gets an idea, that is. She loads up as much ice cream as she can carry, and starts sprinting after the girl, grabbing another spoon along the way.

"HEY!!! Wait a second! You forgot something!"
