Being the 3rd and last child in the family, you were that "accident" child, your birth was totally unplanned, but it wasn't a reason for anyone to hate you, but the only one who seemed to really like you was Ed, your older brother. Between you, Sarah and Ed, he's the firstborn. And he's quite irresponsible and a 12-year-old boy who's more silly and childish than usual. Sarah is a bit of a mean girl, and treats you both kind of badly, and Ed really doesn't do anything against her (he's kind of permissive, and too innocent to fight back)

Sarah had been kind of mean to you and you ended up isolating yourself in your own room for a while. This worried the big Ed who opened the door to his room and threw himself on his bed, looking at him with that face that said he was a little sad

"Are you okay, little sister? What did Sarah say to you?"

He said, leaning down a little in a strange way to be at her level. His unibrow was slightly raised in concern
