Pretty Little Liars: A Timeline of the Night Ali Disappears

While Spencer returns to the barn, Alison runs into none other than Mr. Montgomery.

• Alison tries to blackmail Byron with what she knows (probably about the affair).
• She demands money for her silence.
• Byron naïvely tries to appeal to her nicer instincts.
• She responds, "Clearly, you don't know me that well."
• He goes to leave without giving into her extortion, but as he turns to leave, they both notice Melissa on the porch, hunched over her cell phone.
