<P> The character 's return for the third season happened in `` Blood is the New Black '' , when the Liars have reason to believe that Jenna is faking her blidness when Toby stumbles upon prescription eye drops dated after Jenna 's eye surgery . To test this theory , the Liars planted an earring in the girls ' bathroom at school and remained hidden in the stalls . Jenna is proven to be faking her blindness when she picks up and examines the earring . The girls decided to keep quiet about this newfound knowledge so that they could possibly use Jenna 's secret against her . </P>
