Alice
Alice is one of the first characters we meet, although its not directly shown that she's a student its indicated through the teacher setting an assignment. She’s quite shy but can be loud around certain friends. In the film we see her as one of the main victims. Its clear she wasn’t aware of the danger talking to strangers even though she didn’t say much. We see her as a very innocent girl who's short and sweet.
Jordan
Jordan is another main character, we see her as quite adventurous and willing to explore a bit more. She's also a student at the same college, she seems confident while being oblivious to real life situations and the dangers of talking to stranger.
