In the promo of the episode 5x12 of Pretty Little Liars (
https://www.youtube.com/watch?v=Bk2k8AQtosE ) you can see that one of the PLL's (Emily, Aria, Hanna, Spencer) will get arrested by Holbrook.
I think it's Spencer because the Person who gets arrested had dark nail polish and Spence and Hanna were the only ones with it. Plus, when the Liars get the text message from -A (It's all your fault) you could see Aria, Emily and Hanna, who was even crying. So it might be the case that they first were in the house where the victim was and then Spencer got arrested. After that they left the house and outside they got the -A message. That's why Spencer isn't with them.
Another theory is that Aria gets arrested because of the murder of Shana but I don't think so.
First of all I want to say that I watched EVERY episode, so there might be some spoilers. (season 5, episode 10)
When did you start to watch PLL?
Ooouh I don't remember when exactly, but I didn't watch from the beginning... I think the second season was airing when I watched the first episode.
Who's your favorite character of the 4 Liars and why?
Definitely Spencer! She's so smart and beautiful! But since season 4 I have loved Hanna, too. I never liked crazy Aria, but her name is nice^^
Who's your favorite character in general?
I like Toby, Caleb, Mona, Noel, Melissa and Alison, too but Spencer is absolutely my fave character.
Who is your least favorite character?
Either Paige or CeCe. They are just sneaky. And I can't understand Tom Marin. He's Hanna's dad but never there for her. Awful parent!
Which girl's style do you like most?
Usually Hanna but not this season. Her style now is reeeeeaally bad! I also like Spence's style.
Which girl's style do you like least?
From the Liars I don't like Aria's style. It's just too crazy... In season 1 and 2 Emily's style was very bad but now it's okay.
Which couple do you ship?
Wooow that's hard because I loved Haleb but they are just drinking, sooo.... Spencer and Toby are cute but I want Wrencer, haha. And I'm sick of Ezria ("No, it's not good if we're together") *eyeroll*
I think I don't have to mention Paily.
Right now I want Ella and Byron to be a couple again, that would be so great for Aria and Mike!
Who's your crush on the show?
Caleb and Wren *-* I want Wren to show up again! <3
Whats's your favorite episode? Why?
Uuuh that's a good one... Weeell, I think the Halloween episode from season 3 was awesome! And I liked 4x24 because many questions were answered.
Whats's your favorite scene? Why?
I looooved the scene in season 2x19.

And I like all of the creepy scenes like the one in the 'Vail's Doll Hospital' or on the Halloween train.
What's your favorite season?
Season 3!! <3
What was the biggest shocking moment for you?
When Shana died because she fell off a stage... I mean, seriously!?? Jason survived in the elevator, even Alison survived and Jenna, Aria, Hanna. CeCe fell down a "tower" or whatever.
And come on that Ezra wasn't A was so obviously!
Who do you think has the twin?
I think not Emily, Hanna, Aria, Alison or Spencer. I could imagine someone like Jason, Melissa, CeCe, Paige, ... I don't think that Jenna and Sydney are twins.
Who tried to kill Alison?
I acually have NO IDEAA! There are so many theories, everybody could have done that. I don't think one of the Liars, but maybe the twin of somebody??
Who do you think is a part of the A-team?
We already know Mona (Spencer) and some others were blackmailed. I now start to think about Caleb because he is good at hacking and he has never been suspected...
Who do you think is the Lady in Black/ the Black Widow?
I think the BW is the twin. You can read my theory in my blog.
What is Melissas secret?
She DIDN'T kill Bethany but she BURRYED her.
Who do you think killed Mrs. D, Garrett, Ian and Bethany?
Either -A or the same who tried to kill Ali
What would you change if you could?
I would make -A, BW and the one who tried to kill Ali as different people and in each finale on of them are revealed.
What would you do if -A was after you?
If there would be creepy cops at the police, too, I'd do the same as the Liars. But I would spent time with the people I suspect and if I get an -A-message I'd know that they are not -A.
Who is the mysterious Lady in Black/ Black Veil/ Black Widow?
Theory #1: Melissa
A lot of fans think that Melissa could be BW. She has the same body (very skinny) and she was not at Wilden's funeral, although she did know him. Plus, Melissa is the only Widow on the show since Ian died in season 2. Maybe Melissa didn't want anybody to know that she's in town, so she wore the black veil. And it could be possible that she was somehow connected to Wilden, but didn't want anybody to know about that, too. In any case Melissa is very creepy and she is definitely involved with this whole -A/BW thing.
Theory #2: Somebody's twin
I think this is the most likely theory. A lot of cast and crew members confirmed that somebody will have a twin but it's not Alison like in the books. I could imagine that the BW was either connected in some way with Wilden or she is watching the Liars. Maybe she's #bigA or she is helping the Liars. That would be awesome! If #bigA is the bad twin we already know and the BW is the good twin that we didn't meet yet. This is definitely my favorite theory!
Theory #3 Someone who's "dead"
Recently I read many theories about Maya not being dead. That would be so insane if she's BW. THAT would be a really good reason to wear a mask and a veil so that nobody can recognize her. Remember, we never saw her body! Could it be that Maya is actually alive and helping the Liars? Because I don't see any motive why she would want to hurt them...
Of course it could be a twin of somebody who's dead, too, like Bethany Young's twin.
Black Widow's mask is burned on one side, that could be a connection to the fire in 3x24. Could Red Coat had change her outfit after she lost the Red Coat and it burned? It might be a clue that the BW was present at the fire or somehow connected? Do you think BW is really burned in her face or is it just the mask?
Since we know that CeCe killed Wilden, I could imagine that she went to his funeral incognito. But I don't know why she would threaten the Liars.
So how you can see, I'm quite sure that The Black Widow is a good person and probably the twin of #bigA. What do you think?
