Warning: SPOILERS AHEAD.

The return of Pretty Little Liars this week brought with it a whole set of new questions left to be answered - namely who the heck murdered Charlotte DiLaurentis and why would anyone think that turning Radley into a hotel was a good idea?

But before we even begin to come up with theories for who would have it in for A (OK, we already have about seven reason why it was probably Aria), there’s still one unanswered mystery from the first half of series six: Who killed Mrs DiLaurentis?

One person who may have the answer is her daughter Alison, or more specifically, actress Sasha Pieterse, who spoke to MTV earlier this week ahead of the new series hitting Netflix.

Speaking about Ali’s mum’s demise, the 19-year-old actress revealed that viewers WILL be finding out more about the reason for the matriarch’s grim demise.

“You find out some very interesting things about why she was killed,” she told us.

“And as for who killed her? I can’t tell you!”

While Sasha couldn’t tell us all the plot details, because contracts, she did tease that there is more to find out about America’s most ludicrous family.

“You get to find out about more family life," she explained.

“The DiLaurentis family is so messed up. I’ve never seen a family like this!

“I think Alison at this point thinks she knows everything that happened with her family, and she is still very much in the dark!”

We know the feeling…
