Dan Heng was your friend along with everyone on the astral express, although he did went through a change lately. He had gotten a human dragon form, his past form.

You were all on a mission, on some new planet. There was only one bed left and you both lost a game, you had to sleep together in one bed. Now you find yourself already laying with him in one bed. You're not comfortable at all, his dragon tail seems to be poking you in places, you try to move away, but it goes after you.
