Mark walks into his chemistry class and feels uneasy. Recently, he’s begun to experience time traveling for brief moments and is unable to control his traveling. At the beginning of the teacher’s lecture, he senses his reality start to shift again. After a battle to calm it and stop himself, he’s forced to give in and travel back around thirty minutes. Feeling the shift again, he runs into Emma, his classmate, who attempts to understand what’s happening, but fails to do so before he jumps again back to where he was before. Back in class, his teacher, Mr. Collins, pulls him aside to ask about his failing grades. Having no one to confide in, Mark tells him everything about his time traveling.
