Is any one familar with the pretty little liars sitcom?

The show refers to "The Jenna Thing" as an accident that blinded Jenna. Alison threw firecrackers into Toby's garage as a prank on him, but they blinded Jenna. The four liars were there at the time, so they already know about it. There is an episode called "The Jenna Thing" and that's what the episode is about. If you are referring to a different incident with Jenna and calling it "The Jenna Thing," then we can't help you, because we don't know what you are talking about
