Interesting question. I just assumed it would be mostly the same as a standard bifurcation of the human tongue since it was ripped by Nick's claws, but there is no reason it has to be limited to just that.

The rabbit ran away from the bird lady monster when Fiona fell asleep at the top of the stairs. I think she said she was around 9yo. Whether or not he then trapped it I don't know. Maybe his reluctance to deal with the "poltergeist" was because he was in cahoots with the chicken lady as part of an elaborate ruse. Maybe Nick just made himself look like Fiona's dad when he was making the deal with Tom. Or maybe Tom is much more than he seems to be. Hopefully we'll find out soon

A couple of people have already told you how to salvage the situation. I'd like to give some advice on how to prevent such things in the future, not just with romantic relationships but human interaction in general. Obligatory "based on my experience" and YMMV.

When I was your age (c. 2004) I had recently/would soon come to a few key realizations. Most key, and last learned, was that by constantly overthinking how who might react to which potential situations to the point of in-the-moment paralysis wasn't just holding me back now, I was actively ruining my future. Yes, actively ruining by not acting. Secondly, the -vast- majority of people will have no recollection of the things that you consider so majorly embarrassing they keep you up at night. Finally, and this is more a corollary of the second point, the people that do remember those intactions are extremely focused on how they acted or failed to act. Just like you do.

I'm pushing 40, married my very extroverted best friend 15 years ago, and am still very much an introvert. I also tend to sleep peacefully at night. Well, not night, but that's because I worked third shift until my knees disintegrated

You're right, of course, but at 20 I probably wouldn't have realized that either.
