Toby Cavanaugh (Keegan Allen) is the name on every Pretty Little Liars fan's mind. We're still not sure how to process the reveal that he's on the "A" team, and we're eagerly seeking out any spoiler, clue, or vague hint that helps us figure out what's coming next.

In that spirit, here are the juiciest spoilers about Toby in the Halloween episode and the Season 3 winter season.

Is he possibly good? This is the big question on everyone's mind. The writers refuse to give a definitive answer, but they have dropped some hints. Executive producer Oliver Goldstick weighed in on the theory that Toby is just infiltrating the "A" team to help the Liars, saying "I’m not so sure about that" and reminding people that Toby has good reasons to hate the Liars.

Meanwhile, despite having been quoted in one interview as saying Toby does not have good intentions, showrunner Marlene King has tweeted that it is "not confirmed or denied" if Toby has good intentions.

Is he dangerous? Good or not, Toby is definitely dangerous, at least according to PLL writer Andy Reaser.

Does he love Spencer? According to writer Bryan Holdman Toby really does love Spencer (Troian Bellisario). Huh. Marlene King has also said there's "alwAys hope" when asked about the future of Spoby. But could this ship possibly last?

One of the Liars finds out: One of the Liars finds out the truth about Toby in Episode 16: "Misery Loves Company." Unsurprisingly, "the fallout is huge."

And when Spencer finds out... We're not sure when, exactly, Spencer (Troian Bellisario) will find out about Toby, though Troian Bellisario has hinted that "you can't put much past [Spencer] for very long." Troian has also said that "you're going to see a storm" when Spence does learn the truth.

Dr. Sullivan? We know Dr. Sullivan is back in the winter season. Will her return involve Toby in some way? Many fans think it might, since he is the one who brought her back to Rosewood in Season 2.

Halloween: In the Halloween episode Toby attends the Halloween party with Spencer as if nothing is wrong. So he's definitely keeping up appearances. Creepy!
