In the past, Emily Fields (Shay Mitchell) was always considered the weak link among her friends on "Pretty Little Liars." She was one of "A's" biggest targets, especially after Maya (Bianca Lawson) disappeared. However, a fan of the show recently asked writer Joseph Daughtry, "If A views Emily as the weak link, who do they view as the strong link?" Daughtry's answer was somewhat surprising, as he revealed that "A" has a different opinion about Emily now. So, if Em is no longer the weakest link, who is?
Aria (Lucy Hale)Aria is tangled up in a whole new mess of secrets. She now knows that Ezra (Ian Harding) is the father of a child he knows nothing about, and swore to the child's mother she wouldn't tell him the truth. This is a big deal, especially considering Ezra's brother, Wes (Gregg Sulkin), also knows the truth. Aria and Ezra's relationship has been on shaky ground since the start, but this life-changing information could kill Ezria with just one quick sign from "A." Aria is definitely a possibility to be the new weakest link in the pretty little liars chain.
Hanna (Ashley Benson)Hanna has always been somewhat weaker than the others, in some ways even more so than Emily. One of her biggest early weaknesses were her weight and her former status as a geek. "A" has put Hanna's popular girl reputation on the line a few times, not to mention blackmailed her mother, ran Hanna over, and set up her boyfriend's mom in a car accident. Caleb (Tyler Blackburn) has been the main focus of "A's" vendetta in Season 3, and because the couple are so close, they spent a lot of time sneaking around to see each other. While Hanna has a lot to fear from "A," she finds strength in her relationship, so it seems unlikely that she will be the new weak link.
Spencer (Troian Bellisario)Spencer has been through all kinds of drama at the hands of "A." She's uncovered family secrets, been led on false trails to find Ali's killer, and lost several boyfriends along the way, too. Now that we know she is actually dating "A," it opens up a whole new world of trouble for her. Before Toby was revealed to be "A," the couple slept together for the first time, and it was also the first time we've seen Spencer allowing herself to be really vulnerable. If there is a new weakness in the group, it looks as though Spencer will be the one.
