Summer: almost melts her roommate and destroys her food supply
Winter: accidentally breaks sunglasses
I fail to see why am I supposed to sympathize with Summer here. This is another "idiot character screws up all the time but you have to feel bad for them when they get called out" situation like Patrick Star and Mabel Pines.
I suggest that, if you ever make another episode, you drop this kind of "comedy" trope because it's not only annoying, but many people in real life already act entitled to sympathy when they don't deserve it, and this writing just adds fuel to the fire.
