Despite the fact that Jon liked to look at the two girls (they really were that hot), he wanted to keep an eye on his mom. She was going upstairs ... and Zoe was upstairs. He almost felt like a referee, trying to keep his mom and his sister apart.
He walked up the stairs and peeked around the corner. His mom appeared to be just leaving her room, with a different shirt (a halter top) and her purse (which looked like one that a teen girl would have). She walked towards Jon's direction, but then stopped in front of Zoe's door. She glanced towards the bathroom door, then turned back and smiled.
Jon watched her move out of view, presumably walking into Zoe's room.
"What's she doing?" Jon said quietly. He moved towards Zoe's door and peeked inside. His mom was looking at one of the walls, for some reason. Jon glanced towards the bathroom door. It was closed, meaning someone was using the bathroom. It had to be Zoe. He looked back at his mom and was shocked when he saw her take out her dark pink lipstick from her purse and write the word FREAK over all of Zoe's posters. When she was done, she smiled and said "I'm a genius," to no one at all.
Jon dashed into his room and kept the door open just enough to see his mom walk out of Zoe's bedroom and around the corner to the stairs.
About ten or fifteen seconds later, Zoe came out of the bathroom and saw Jon peeking around his door. "Jon, what are you doing?" But, when she saw the look on Jon's face, she knew something was wrong. Very wrong.
She immediately ran to her bedroom, saw that someone had vandalized her posters, and screamed "Fuck!"
Downstairs, Jon's mom was just leaving with her friends. And when she heard her daughter scream, she displayed Sarah's trademark smirk, again.
"Come on, girls. Let's go."
And they left to go to the mall.
