As one couple prepares to swap wedding rings on Tuesday’s Pretty Little Liars (Freeform, 8/7c), another could be squeezing into handcuffs.

Though we don’t technically know which Rosewood pair will make its way down the aisle — Caleb and Hanna got engaged last night, joining Aria and Ezra on the road to holy matrimony — we do know that the couple’s path to happily ever after is, well, swarming with cops.

TVLine has an exclusive batch of photos from the episode, in which Aria and Ezra have a close encounter with a phone-confiscating police officer. Additional photos find Spencer, Caleb and Mona teaming up with “Emison” to get to the bottom of… whatever new mystery pops up this week.
