Pretty Little Liars: Top 5 Moments From "Let the Water Hold Me Down"

Last night's Pretty Little Liars saw many revelations and OMG moments.  Most of our couples are on the verge of collapse, while the girls inched closer to figuring out A’s identity. 
 
1.  Does this prove Garrett and Jenna are A and killed Alison? – Spencer (Troian Bellisario) finds a stash of A’s things at her lake house, proving A’s really been hiding there, and creeping all the girls out. A receipt for some place in Philadelphia intrigues the girls, so Spencer and Aria (Lucy Hale) hop on a train. After they split up, Spencer figures out there’s a blind school nearby and after talking to a student who looked like an Abercrombie model, and stealing a sign-in book, Spencer finds out Jenna stayed there for a year and worked really hard to get out because she was driven by revenge. On the night of Alison’s murder Garrett signed Jenna out.
