We don't trust Spencer's (Troian Bellisario) dad Peter Hastings, and a recent tweet from Pretty Little Liars showrunner Marlene King makes us even more wary of the wrathful Hastings patriarch.

After reaching 40,000 Twitter followers (wow!), Marlene tweeted this juicy detail about tonight's episode, Season 2, Episode 22: “Father Knows Best”: "Papa Hastings has a secret and it's not that he's Mrs. D's baby daddy."

Obviously, the Mrs. D here is Mrs. Dilaurentis, aka Jason's (Drew Van Acker) mom. So now we know for sure that Jason's true parentage isn't the only secret Spencer's dad has been keeping. 

Hmm...We wonder if what he's hiding will make us more or less suspicious that he's Ali's killer.

Be sure to tune in for the next episode of Pretty Little Liars tonight on Monday, February 27 at 8 p.m. ET/PT on ABC Family.
