Tip and munchausen's syndrome.

I actually got to thinking about Tip's situation being like the kids who have a particular genetic issue. Forgive me, I do not recall the name of it, where you're born seemingly female with slightly underdevelopted sexual features, so you grow up a girl/female, then puberty hits and BAM, you develop male genitalia, a deeper voice, facial hair, etc. Tip is just has this backwards of this genetic condition.

As for the relationship with Mombi, I would say that has to be part of what is making Tip so freaked out right now. You've got this idea that Mombi did take care of Tip- feeding, bathing, changing diapers, tucking in at night, etc. So there is an attachment, even if it is reluctant or because Tip had no one else. Plus, there's how now Tip is learning that Tip started out female and Mombi is the one who gave Tip the elixir that made Tip feel/appear male, and without it, Tip is regressing back to Tip's birth form of female.

Then add in, at some point it has to have hit Tip-- why did Mombi do this? What would make you fake a child's sex to be the opposite of what they were born as, why would you hide them from all the world, and why would you lie to the child about everything? Heck, Tip might even wonder what name Tip had at birth- was it Lizzie or maybe she hadn't been named before Mombia got the baby and gave the baby both a name and the elixir. Plus, Jack kisses Tip, and for all we know Jack may not have cared if Tip was male or female, or that may have been how Jack's feelings shifted when Tip suddenly became female, so Jack may be almost as confused as Tip or he may be where he doesn't care what body holds Tip as long as it's Tip inside. But either way, that kiss clearly freaked Tip out and Jack's attempts to soothe and calm his friend, had the opposite of their desired effect.
