Sam is trans-man, who's family is from Mexico. He has a slight studdering issue, which is really shown in M and T words. He has extreme anxiety and public speaking is next to near impossible for him. He is also secretly a famous street artist going by the name of VOP, or voice of the people without anyone else knowing. He does spray paint art centered around major societal issues.

For his first line, he's being really quiet after William simply says Hi. He's worried Will is mad because the teacher had asked Sam to answer a question that Will couldn't.

For his second line, he's trying to read his essay he wrote, that he's having a really hard time saying in front of the class.

for the third line, Will catches Sam spray painting on the side of a store on the memorial where someone died. Will doesn't realize its him, but see's the art and chases after him, discovering it was Sam that was VOP all along. Sam, being nervous about someone knowing who he really was, says this line.
