Pretty Little Liars Spencer is teetering on the edge of a relapse.

'Pretty Little Liars' Season 6: No Halloween Or Christmas Special; Is This A Bad Idea?

The Rosewood teen has a history of addiction, and the lingering memory of the Dollhouse has her reaching for the pills once more. Spencer (Troian Bellisario) may not be able to get her hands on her own batch of drugs, but the wily character is quick to consider other options. Aria's (Lucy Hale) sleeping med, Spencer's sleeping meds, it's half dozen of one, six of the other.

All that's left if for Spencer to pop a handful and tumble down the rabbit hole. Unless she can resist the urge, that is.

She has an addictive personality," Bellisario recently said of her character, according to She Knows, explaining that even her search for 'A' feeds into that dangerous trait. "I think that whether those are explored through her past with drugs or her past with her following her sexual impulses, there's always something about her personality that's going to be addicted to the wrong kind of thing."
