PLL Theories

Wren is -A theory Part 1!

So I gathered a lot of information about Wren and I think I will need to put it in two parts so here's part 1!:
- 4x10, Mona corrects Wrens spelling on the word 'diagnosis'. I know people make mistakes but he's apparently a doctor so I think he should write that word a lot.
- Could it be possible that Wren became a doctor just to have access to pills and maybe even documents? If you looks at the things that happened to the Liars, most of it contained drugs or some sort of pills. Someone even stole Alison's autopsy report! And who has access to that? Hmmm...
- Probably most common reason ever,
UK: Nosey
USA: Nosy.
Remember when -A vandalised Dr Sullivan's office? "NOSEY Bitches Die" was on the wall...
- In 2x21 we see Spencer and Wren having a casual make-out session in Wren's apartment, he said something about his OCD, that he can't fall asleep unless all his books are in alphabetical order... Remember -A's lairs, where all the hoodies are all neatly spaced out. OCD much, -A?
- 3x01 when Hanna went to visit Mona in Radley and was looking through a magazine. She said "Birds, Birds, Birds. You can't find a top THIS SEASON without feathers on it." Um Wren is a type of a bird. And THIS SEASON? I don't see it like Summer or Spring. I see it as Season 3. So is Season 3 all about Wren? Maybe because Wren is all around them.
-4x10 Wren also writes with all Caps. Who else writes in all Caps? -A! See when Spencer had a steamy shower and there was writing on her mirror in ALL CAPS.
