Hey, remember when a mysterious someone pushed Ian Thomas (Ryan Merriman) off the bell tower during the Pretty Little Liars Season 1 finale? The show has yet to clarify who exactly showed up at that fortuitous (for Spencer [Troian Bellisario], anyway) moment, but a spoiler-y new tweet from showrunner Marlene King tells us when we might find out more of that story.

A fan asked Marlene King via Twitter, "Which A threw Ian down the bell tower?"

Marlene, excitingly, responded: "A sort of answer in 401!"

A "sort of answer"? We'd rather get a full answer, but we'll take what we can get. We're just happy that Ian is going to be revisited.

We wonder if this answer is related to  Marlene's promise that we'll eventually learning who actually killed Ian, after he miraculously survived the bell tower incident.
 
Who do you think pushed him? So far, the only member of the “A” team who appears to have had the strength to pull Ian is Toby. This would imply Toby has been fooling the Liars since day one. Do you agree? Share your theories below!
