Cross's thoughts: He's probably thinking about other people.

Dream's thoughts: How the heck does Rapunzel keep her hair so clean? Is it naturally clean like that because of the sundrop? Does it clean itself whenever she sings the Healing Incantation? Does she slave over it for hours on end?

Dream's thoughts: Did Mother Gothel whip up some sort of unethical and harmful antidote that eliminates oils, hair grease, and dandruff? That sounds like something she'd do. I mean to our knowledge she's the only one who knew about the power of the sundrop flower and the only one who knew the Healing Incantation, plus she completely withered into dust in a matter of seconds at the end, so I wouldn't be surprised if she's actually some kind of demonic sorceress in disguise.
