Pretty Little Liars: A Timeline of the Night Ali Disappears

As luck would have it (probably not luck, since this is PLL) Mona happens upon the bedraggled Alison.

• She loads Alison into her car and takes her to the Lost Woods Resort.
• Mona convinces her to fake her own death.
• Mona helps Alison get all the necessary items for her full transition into Vivian.
• The two part ways. Alison drives away, leaving Mona standing in the lot with a cryptic smile on her face.
• Mona is still so nice and meek, so in exchange, Alison instructs her on how not to be a loser.
