It is really weird when these two are this close. Neither particularly likes to be near the other. They tolerate each other mostly. But I have to wonder if Haley knows Mickey is sick -- for those who don't know he has cancer. Just before this photo was taken Mickey puked. When he was done he crawled into this bed. A few minutes later she snuggled up next to him. Maybe she likes him more than she lets on.
Update: Mickey passed away 5 days later. Haley knew.
