The Jenna Thing (situation)

The Jenna Thing is an event where Allison, Aria, Emily and Hanna blinded Jenna Marshall.

It started when Allison spotted Toby keeping through her bedroom window (later proven to be a lie). So to get revenge Allison and the others went to Toby's house to set off a stink bomb. Aria, Hanna, Emily and spencer wanted to go back but Allison wouldn't let them. They didn't know that Jenna was in the garage so by accident they set off the stink bomb. This winded up blinding Jenna. This is one of Aria, Hanna, Emily and Spencer's big secret.
