Nope, because that's not Claire's phone

Claire's relief left just as quickly as it came.

"That's... not my phone." Claire said in disappointment.

Anna took another look at the phone. She was right, it wasn't hers. Claire had a smartphone, whereas this phone was clearly some sort of burner phone, being old and cheap looking, as well as lacking many of the features that Claire's smartphone had.

"You're right, but whose is it?"

"I don't know! I'm just as lost as you are!"

"Well, try to unlock it and see!"

Claire obliged and unlocked the phone, which was quite easy as there was no passcode protecting it. She saw there was one notification, a text message, which must have been the source of the buzzing they heard a minute earlier.

"There's a text, should I read it?" Claire asked, feeling nervous and a bit sketched out by now.

"I mean, yeah, might as well."

Claire's finger shook lightly as she opened the text, and began reading it to herself. Anna moved in closer so she could read it too.

Attached was a picture of two sets of uniforms. Anna's and Claire's mouths both dropped upon reading this. Their clothes were in the hands of a mysterious stranger, who was threatening them with prolonging their embarrassment even further by keeping their clothes.

"Claire, we need to go, now." Anna told her friend.

"Are you nuts? The band room is practically on the other side of the school!" Claire exclaimed with wide eyes.

"Which is why we need to leave ASAP. We only have five minutes!"

"What if it's a trap? We'll be seen!"

"Uh, I hate to break it to you Claire, but you've already been seen naked. So have I. We might as well try and get our clothes back. I don't exactly want to stay naked for the rest of the day!"

"I don't know..."

"Well we don't really have any time to sit around and think, do we? I'm leaving now, so if you at least want a chance to get dressed then I recommend coming along." Anna said, grabbing the phone and heading towards the bathroom door. "Otherwise, good luck..."
