Carlos is Gonna Get It (foreshadowing)

I'm towards the end of the book, In the middle of the book she was kind of friends with Carlos, she was starting to help him out and talk to him a little. But now it's a little more towards the end of the book ,she starts ignoring him because her friends make fun of her. I believe that when it comes to the time when they decide to prank him, Trina will defend him or back out of the prank.
