Escapes and Reversals

Lexi was planning to surprise Jesus in person. The whole family kept Lexi’s visit a secret thinking Jesus would be happy to have his long distance girl suddenly within distance. And it’s not their fault that they didn’t know about Emma. To them Emma has only ever been Jesus’s friend and teammate – nothing more. She was actually on her way to becoming more than just his friend though. So Lexi’s visit turned out to be a surprise for her as well. Jesus only had seconds to warn her that his girlfriend had returned before Lexi introduced herself to Emma at school. Emma was caught off guard and accidently inured her finger with the simplest task of trying to close her locker. Lexi was so proud of Jesus and she wanted to take a picture of him and send it but she couldn’t. Her inbox was too full. She checked to see what she could delete and found Jesus’s message waiting for her. He though he had deleted off her phone when in fact he didn’t. So she read his breakup email. Lexi couldn’t pretend that everything was fine though. She ended up lying to him to protect her feelings. She told Jesus that she had kissed someone else and that she needed time for herself. Instead of him breaking up with her; Lexi broke up with him.
