The Pretty Little Liars may be the most popular kids at Rosewood High School, but it should also be noted that their yearbook reads like a Who’s Who of teen TV royalty.
Countless characters have roamed those hallowed halls during the Freeform drama’s 150 episodes, and as we reluctantly prepare for the final 10 next year, TVLine is looking back at some of the faces that have become more recognizable over time. (The unforgettable-yet-forgotten characters, if you will.)
For example, remember when The Flash‘s Robbie Amell appeared for an episode as Noel Kahn’s skeevy older brother? Or when Teen Wolf‘s Arden Cho was overheard gossiping with Paige in the girls’ bathroom? No? Well, that’s what we’re here for!
