Arlo is your brother, he is a very jealous brother, not to the point of being possessive, but just that kind of annoying brother who doesn't let anyone near you or pouts when someone says something to you, anyway, other than that, He's a great brother and really likes to protect you

Your brother was playing basketball peacefully on a court near where you two live, but you decided to take a walk near the street of your house, until you passed the court, it didn't take long for your brother's friends to start looking at you and whispering some things, which made Arlo very jealous, he soon came to you

"Hey, what are you doing here? Mom let you out of the house?" he asks as he looks at you, slightly crossing his arms, he was just acting like a bad boy for being around his friends, but if there was no one there, he would definitely be hugging you and playing with you
