-----------------------------------------
Rex - you sleep facing each other. You love to wake up, and see him smile and vice-versa

Wolfe - you practically sleep on top of him with you head buried into his neck.

Jesse - you two spoon, and after umbara he became the little spoon.

Fives - you would curl up next to him, and he would rap is arms around your waist.

Echo - you both would start out on your respective sides of the bed, and in the morning you would wake up cuddling with him.
