Jackson finished slipping on his gloves when he saw testicle left and right, aka Scott and Stiles, walking out onto the field with a girl, a cute one. Now what would a cute girl like you be doing with them? He continued to watch from afar until he heard coach Finstock yelling for him to practice with Danny.
He rolled his eyes and grabbed his lacrosse stick but stopped short again when he noticed you laughing with them. It was bothering to watch for some odd reason but the thing that really bothered him was when you hugged Stiles. He didn't understand why it bothered him but it just did, so being the person he is he decided that it'd be fun to steal your attention away from those two dorks.
"Jackson, if I don't see any goals being made I swear that you'll be sitting on the bench with Stilinski, and you Stilinski quit dallying around with your sister and get your ass over here!" Coach finstock shouts catching Jackson off guard, but he can't help but smirk knowing that you weren't interested in the two idiots but quickly the smirk turned into a frown when he actually realized that you were one of the idiot's sibling.
