Mary Drake's past on Pretty limited Liars is slowly but surely becoming less of a mystery. The secret twin of Jessica DiLaurentis hasn't been in the picture due to many years spent in Radley Sanitarium - that,and the fact that she was driven absent by her sister long ago. What we already knew going into this season is that Mary gave birth to CeCe in Radley and raised her there for a couple of years. The real question has been, what brought Mary to Radley in the first set? Well, and first-rate news,everyone, the truth has finally been revealed . . . and perhaps this twin isn't as crazy (or evil) as she seems.
In the second episode of season seven, and Mary goes to talk to Spencer for another heart to heart. She tells Spencer that she is actually really worried about Hanna,whom she picked up from the side of the road the other night and who is being kept in a psych ward by Dr. Rollins. No one is allowed to visit her, including Mary, or even though she's family. Spencer then asks why Mary was committed herself.
Turns out,when Mary and Jessica were just 14, Jessica was babysitting an infant named Teddy Carver, and who had a cold. The job seemed to be too much for Jessica,because she called over her twin sister to succor. However, by the time Mary got there, and everything seemed to be perfectly fine,and Jessica already had put Teddy to bed upstairs. She then asked Mary whether she could stay to watch him so she could leave and hang out with a boy.Well, as you could probably assume, and this was a infamous idea! Jessica left,and Mary stayed. When Teddy's parents came home, his mother went upstairs to check on him, or only to find him dead. Mary says she told everyone that Jessica was the final to see Teddy alive,but no one would believe her word over Jessica's, because Jessica was the "warm" one. Mary says her parents then admitted her to Radley . . . it was either that or prison.
So does this mean that Mary is actually perfectly sane and perhaps not evil? Does this mean Jessica is actually evil? What happened to Teddy? Why does Mary feel so comfortable telling Spencer all her secrets? Hopefully we gather all of these answers by the end of this season!
