pretty little liars how did jenna go blind
Jenna Marshall One evening, Ali convinced the others to support her plan to get revenge on Jenna's stepbrother, Toby Cavanaugh, for spying on them while they were changing. Ali snuck into the Cavanaugh's yard, grabbed one of Toby's fireworks, and accidentally launched it into his tree house. Alison sees Toby and Jenna together and accidentally set the firework off into the tree house, blinding Jenna and burning it down. Alison blackmails Toby into taking the blame for the incident and he is sent away. Later the girls would come to call the infamous incident "The Jenna Thing."
