The mystery suspect, Cyrus, confesses to kidnapping Alison with details that exactly match what she told the doctor during her exam.
Initially, Alison hesitates to identify Cyrus as her "kidnapper", and the liars worry that she will ruin an innocent person's life to save her story. Spencer thinks the girls should tell Tanner the truth, so that Ali doesn't have a chance to throw them under the bus.
However, when the Alison's tape recording disappears, she begins to suspect that Melissa is somehow involved.
Meanwhile, Emily continues to support Alison and believes that she won't identify Cyrus. Alison tells her she does know Cyrus, and he stole her things and left that scar on her thigh. Emily is disappointed when Alison does identify Cyrus and ends her friendship with Alison.
Alison is later shown meeting with Cyrus in the woods. She gives him a plane ticket so he can disappear and alludes to the fact that their initial encounter was not exactly as she described it to Emily.
