Previous episode recap, in 140 characters:
Brit in, Riggins almost gone, and Spencer almost sex. Earring memories Aria once grungy. Girl ain't blind, Mona is cray. Secrets lies LIES?!
When we reunite with the Liars, we find them, per usual, in the school courtyard, scheming. This time, they're side-eyeing Jenna (still pretending to be blind), trying to figure out how to bring her down. The only move they have right now is by way of Aria, whom Jenna previously asked to accompany her in a piano recital. Aria's obviously not pumped about being the pawn in this plan, but it looks like she will go through with it, mainly because there are no other options. Well, that is except for Hanna's plan, which is:
"We should push a table in front of her and see what happens."
So yeah, Aria it is.
