Pretty Little Liars: A Timeline of the Night Ali Disappears

Before they can get very far, Jenna and Garrett run into Alison in her backyard and they argue.

• An anemic slap fight breaks out between Ali and Jenna.
• Jenna stumbles and Garrett gets between the two girls.
• He pretends to beat Alison with a hockey stick he took from Jenna, because isn't that the next logical move?
• Garrett lets Jenna think he's beaten Alison to death, saying vaguely, "I took care of it."
