All of the liars received their keepsake items from Ali’s grave except for Spencer Hastings. Why is that? Well through binge watching PLL we’re beginning to think that perhaps Spencer’s keepsake item was never shown because we’ve been seeing it in the ‘A’ closings.

I got this little idea after watching 3.06. In the episode Spencer is with Jason at the April Rose store and I never noticed this until today, but Spencer is bending over looking at the knives in the casing.

I was very curious as to why the camera was so focused on the knives, it made me think that perhaps Spencer was looking for her knife. I know this seem crazy but Spencer’s keepsake item was never returned to her and the 'A’ closing scenes have been showing an 'A’ member with a knife in even more episode closings. Another thing is that neither of the girls knew what the other placed in Ali’s casket so it’s not that weird that Spencer could have placed a knife in the casket.

Aria got the earrings that she thought belonged to Meredith, the ones that Ali planted in the cushion of the sofa in Byron’s office.

Hanna got her ouija board back in 3.07. This was the board that she and Mona used one night Hanna saw Ali on her patio.

Special note: Spencer was looking at the knife casing in the April Rose store in 3.06. According to the episode order with Aria and Hanna both receiving their keepsake items from 'A’ this was a clue that Spencer was nervous about her item returning.

Emily receives one of her postcards in 3.18, with a message from 'A’ written in French.

The knife we are referring to was first spotted in the Pretty Dirty Secrets Halloween Webisode titled 'Call Security’, watch them here. This time period was between episodes 3.12 and 3.13.

A crazy thought that’s been running through my mind is that what if this knife was used to make the slice that was shown on Ali’s thigh in 5.04. I know Ali mentioned Cyrus gave her that scar but let’s be real here, that flashback was not real compared to the others we’ve been shown in past seasons. Therefore, I don’t believe it was true at all, I believe it was made-up to kill time so that Cyrus could leave the precinct.

Another clue that may suggest that a knife was used to produce this scar is the the doctor mentioning “a knife” Haha. Adding on to that “the scarring is more consistent, a slice rather than a puncture,” meaning that someone made the slice using a steady hand with a knife not a screwdriver, or even a rock for that matter.

Therefore, I believe that Spencer’s keepsake item that she put into the grave with Ali was the knife that 'A’ is using. I think that’s why this object is so important and shown so much in the 'A’ closings. It’s very important to the storyline and the writers not showing us her keepsake item is a possible hint that perhaps Spencer’s item is something major.

Mona told the liars in 3.24, that Redcoat wore a mask and Sasha confirmed in the Halloween Special (which I believe was a secret revealed as Marlene and ABC family tweeted there would be secrets revealed), that she was Redcoat.

“I was Redcoat. I was myself with an Alison mask.” - Sasha Pieterse.

If Alison was the Redcoat with the mask and Mona mentioned to the liars in 3.24, that the redcoat with her at the grave wore a mask then it’s hella possible that Alison ordered Mona to dig up her own grave just as Hanna mentioned in 3.18 to Emily and Aria when Emily remembered that Redcoat was there the night that Ali’s grave was dug up.

If Alison had Mona dig up her grave then Mona and Ali had possession of the keepsake items meaning Ali could be the one in possession of the knife. So let’s backtrack.

I mentioned above that perhaps Ali’s story was a lie (edited it), so let’s say that it was true. This would mean that Cyrus cut Alison sometime during 4A and it would explain the Redcoat that was sleeping underneath the DiLaurentis house because they had no where else to go. No money, no place to hide.

In comes Shana (4.18, Shana needed the money from Ali’s picture because at this time Cyrus had stole all of Ali’s money, the 50k that Jason paid for Ali’s remains to be returned. Who Jason Paid the $50,000 to theory). So this is why we see Alison contacting Shana in 4.18, because at this point Cyrus had taken her money.

So if Mona was working for Redcoat and blackmailed Lucas to call Jason about the body under Redcoat’s orders then the money was given to Mona by Lucas, and Mona gave the money to Redcoat after she made Spencer believe that Toby was dead.

Which explains why Alison mentioned in 5.05 “I mean, Spencer you landed in Radley because of one those elaborate stunts she pulled.” It always bugged me, how did she know about that?

More to come to this theory, stay tuned!!!
