Was Paige really being as unfaithful as it appears? A sneak peek of Season 3, Episode 18: "Dead to Me" clarifies.

As you can see in the sneak peek below, Paige wasn't cheating at all: she was trying to track down who wore the Queen of Hearts costume at Halloween. The woman she was "flirting" with worked at a costume shop.

As dedicated fans know, the "mystery woman" isn't actually so mysterious: It's Shana, a character we met during the PLL web series, Pretty Dirty Secrets. And as PDS viewers know, Shana is an employee at a costume shop, so Paige's story checks out.

See? It appears things are a-okay for Paige and Emily (Shay Mitchell).
