Don't get me wrong; the entire point of my post was that I have no idea what will happen and so I really have no theory to defend here. But:>No, because Tom seemed to know what the blood moon does and wanted him and Star to be under it. He's not suicidal.
Tom could be as uninformed as Star and Marco are + going by how S3 established that he and Star were known for their Silver Bell Ball dances in the past, him wanting to dance with her could have also just been him wanting to recapture the feelings of their prior relationship by sharing the most important dance of the night.>Opposite of a curse.
That's just one aspect of it: something good happens, it seems good, you find out it's just one aspect of something larger that's bad.>Too convoluted and no evidence of this.
That's why I said it could be "something" like that; it's not a theory I'm pushing.
Although I would say evidence of the link between them would be Marco using the wand: what I was sort of getting at is if they can be connected in a positive way, perhaps it also works in the reverse and something negative affects them both as well. The point of it being a big plot episode is that something in it will certainly be a surprise that the audience hasn't seen coming.
Again, no real theory here. I do think it's unlikely that the show will go "Star and Marco's feelings for each other were a curse all along," if only because it seems too obviously the endgame pairing and that'd be a pretty difficult obstacle to work around + this show doesn't seem like the type to pull that kind of obvious fuck-you move to the fanbase if the point is that they won't end up together in the end.
I don't even ship it; I'm just going by what I feel the crew would/wouldn't do.
