Cosima is a mattress hog, and I get the feeling that this is a very calculated move on her part.
Like, it doesn’t matter how evenly the bed distribution ratio starts off, she’ll inch closer and closer to you so slowly that you don’t even realize that you’re subconsciously moving toward the edge, and then next thing you know you’re pressed right up next to her with nowhere to go.
Or she’ll wait until you’re curled up on the edge of the bed, and then faster than the speed of light she’ll scoot right on over, so your only options are to cuddle with her or fall to the floor.
Because she was so disbelieving that someone wanted to be friends with her that she automatically thought it had to be part of an illegal experiment. So it doesn’t even occur to her that someone would cuddle with her so willingly.
Anyway the point of this is that Cosima is a giant snuggle monster who will trap you in her tangle of blankets and sweaters.
