favoriete episode and why?

mine is episode 20 because everyone is getting along well most of them and when toby and spencer get together

2x11 "I Must Confess." I love it for a lot of reasons, like the main confession about A, Maya coming back, Spoby make out, Aria and Mike scene, and two of my favoriete songs are in it, three if u count the theme song.
(No meer Wishing door Hayley Taylor, and this one which is my all-time favoriete song.)

Mine is the first secret because it shows how it all started and it gives u hints on who is A and it shows how alison was a little bitchy if u ask me no wonder somebody murdered her i mean seriously

Halloween event a.k.a "The First Secret"
Because it shows everything from Ali's perspective, and it shows what actually happened (not the blurry memories that the other girls have). Also there are a lot of clues ! :)

sereis 2 episode 15 i luv how they fight to trick A
