Keegan Allen (Toby) and Troian Bellisario (Spencer) are such spoiler-teasers, but we still can’t help but love the Pretty Little Liars stars. Check out the photo Keegan just shared of the two keeping secrets together.

“The moment we found out @SleepintheGardn haha #pll,” Keegan captioned the photo of he and Troian looking like they were just made privy to quite the PLL revelation. In the pic, Troian’s eyebrows are raised in surprise and Keegan’s jaw is dropped. What did these two just find out?!

This isn’t the first time these two have dropped a hint that there is a big reveal coming in Season 5. Earlier this week, Troian captioned this photo of Keegan looking at showrunner Marlene King (aka the Holder of the Secrets) in shock and awe: “Storytime with Mar. trust me. You all are so sad you missed out on this one. (Now keegs and I can really be know it alls).” Are these two just pulling our legs, or are there some serious secrets being told on the Pretty Little Liars set?

Let’s go ahead and assume something prompting these pictures. If something is set to go down and Marlene is telling Troian and Keegan about it, then it probably involves Spoby. Right now, these two are in a relatively solid relationship. Will that change in Season 5? Will whatever secret these three are holding bring Spoby closer together, or will it tear them forever apart? We’re hoping it’s the former, but secrets tend to be destructive on this show. Not to mention there’s still much we don’t know about Toby and his recent trip to London. Will his whereabouts at the end of Season 4 come into play in Season 5? Does this have anything to do with Toby’s late mother? Or his relationship with Ali? We’re ready for Season 5 already!

What secret do you think Keegan and Troian are teasing? Sound off in the comments below!
