The girls dig deeper into Alison's past. Check out our guide for season 2 episode 23 of Pretty Little Liars, "Eye of the Beholder":
The Liars come across someone from Alison's past who could hold the key to what Ali knew before she went missing.
- Aria, Emily, Hanna and Spencer are on the quest for answers of what Alison knew before she died and they might have just gotten a big lead when someone from Alison's past appears.
- Duncan (Lachlan Buchanan) might hold the key to all of the girls' answers, but can they trust him to let down their guard?
- And just when they feel like Duncan may be the only lead, Jason drops off a bag of Alison's personal items that could be more than just a bag of junk.
- Meanwhile, Toby's return to Rosewood brings a surprise reunion that ends dangerously.
