Theory!! So the first lyrics of the song say "Some of them want to use you" and it shows Seraphina, showing that she uses people. Then the next lyrics are "Some of them want to be used by you" and then shows Tintleaf, who has a well known crush on Seraphina. This shows that Tintleaf likes her so much that he is willing to be used by her. I think that Seraphina is going to use Tintleaf, and he either won't know or won't care. The next line of the song is "Some of them want to abuse you" And it shows Coppertwist. This is no surprise, as I thought Coppertwist was a jerk. This mean that he is abusive to people, which means he hurts them. The next line is "Some of them want to be abused" and it shows Nil, who loves Coppertwist. I think this shows that she is willing to be abused by Coppertwist. I think that Coppertwist wants Seraphina to love him for his own reasons, most likely because he thinks she's pretty, and doesn't actually love her. He will probably will abuse her, both emotionally and physically, and is most likely already abusing Nil. That is all the theory I have in my today so bye!
