There is simply no way any human should eat that much pie in one sitting! The volume of the scene is also on full blast — you hear every sniffle (she is crying while she eats), every gulp, every slurp, every time the fork tip hits the pie container. As you're watching, you know what's going to happen. We've all been sad, or drunk, or stoned, or depressed and stressed, and tried to fill the voids in life with food. And you know what happens? You throw it all up. And so did she. So not only do we get to see M shovel an entire chocolate cream (and apparently gluten-free) pie into her mouth for an eternity, but then we get to watch and hear her vomit it all up while C watches in his XXL sheet from the other side of the room.
