Pretty Little Liars showrunner Marlene King has already told us to “expect nothing but the truth” in the Season 4 premiere, but we’ve learned to take these kinds of promises with a grain of salt. PLL writer Bryan Holdman’s recent tweet, however, has us believing we may be getting many of the answers we’ve been waiting for since the Halloween train episode...

This year’s Halloween episode may have been the creepiest of the season, and we’re disappointed that so many questions still linger from it. Who killed Garrett? Who attacked Spencer on the Halloween train? Who very nearly killed Aria? Bryan promised these answers and more in the Season 4 premiere:

“Better not miss 401 if you want those answers. Someone is spilling it. Big time,” Bryan tweeted early yesterday morning.

Could it be Mona, who has become more talkative now that “A” has “kicked [her] to the curb”? We know that she will be a Liars adjunct in at least the first few episodes of the season. If this is the case, we imagine the Liars will be demanding answers in exchange for group membership.

Are you excited to finally learn the answers to these questions? Who do you think is spilling all of their secrets? Let us know in the comments below!

Catch the next episode of Pretty Little Liars on Tuesday, June 11, 2013 at 8 p.m. ET/PT on ABC Family.
