Theories/clues 3x06

When Spencer and Jason talk about the "films" that the NAT did he mentions that they had girls working for them and im guessing that those girls would be Jenna and Melissa because the liars assumed they were in the NAT club! He also said maybe Ian filmed it for someone else, could he refer to Alison or A? hmmm.

Jason says "What sister is it exactly that you talk about since it turns out i have more than one" I know that he is most likely referring to Spencer, but that could all just be a lie made up by the hastings and there might be a secret hint that Alison has a twin.

Holden and Maya used to see each other? I dont remember if it was Holden or somebody else but i know someone went to that true north school with Maya, that may be how they met and if so, Holden would have been doing some kind of drugs which means, he would have access to drugs!

I wonder if Ezra is lying and really got the money Jason gave away, but Jason didnt pay cash, he wrote a check right?
