It’s been far too long since we’ve seen Rosewood’s resident toolbag Noel Kahn (Brant Daugherty), and we want to know what he’s been up to. This is a boy who has dated both Jenna and Mona, blackmailed Ezra, and has been a general Liars nuisance since Day One. But, with the recent Pretty Little Liars reveal that Ezra is “A,” we can’t help but wonder if Noel is, in fact, smarter than he looks. Did Noel know Ezra was “A”?!

Here are some reasons this theory might have merit.

He Blackmailed Ezra for an “A”

In Season 1, Noel blackmails Ezra into give him an A (an “A” get it?!) on an English test. He writes “I see you” on Ezra’s car. And he is framed for stealing test answers by “A.” At the time, we thought this sequence of events was all about Ezra’s secret relationship with Aria, but what if it was about Ezra’s possible past involvement with Ali, and his “A”-like behavior? In theory, Mona was actually “A” during this time period, but what if she was still getting her orders from Uber “A”? Could Noel have figured this out?

He Dated Mona

In Season 2, Noel dates Mona aka the Original “A.” We’re not sure how much Noel knew about his girlfriend’s involvement in the “A” game. According to Mona, he was the one who broke up with her. Could he have found out about her involvement, and dumped her? Or perhaps she even told him? If Ezra was involved in the “A” game at this point, Noel could have had glimpses into his scheming through his relationship with Mona.

He Dated Jenna

In Season 3, Jenna and Noel date for awhile. The match was kind of out in left field what do these two even have in common? unless they are both somehow in the “A” know. If Noel didn’t already know about Ezra as “A”, could Jenna have told him? After all, she knew something important enough to have someone try to kill her in Season 4. Could her information about Ali’s “death” have something to do with Ezra? And did she share it with Noel when they were dating?

He’s Preoccupied With Ezria

In Season 3, Episode 9: “The Kahn Game,” Noel grills Aria during a game of Truth or Dare about her relationship with Ezra. At the time, it seemed like he was just being bitter and jealous, mad at Aria because she dumped him to go out with Ezra but now we wonder if it has more to do with the fact that Ezra may be “A”. Perhaps, Noel was even trying to suss out Aria’s involvement in the “A” game. For all he knew (or we know, for that matter), Aria could be complicit in Ezra’s schemes...

Noel Blames the Liars

In Season 3, Episode 13: “This Is a Dark Ride,” Ezra bursts onto the Halloween train. He claims that he followed the tracks until he found it. Literally seconds later, Noel confronts the Liars about their involvement in Garrett’s murder, telling them, “Why don’t you tell the cops you did it, so the rest of us can go home.” If he thinks the Liars are working with Ezra/“A” (which, given how close Ezria is, makes some sense), then we can understand why Noel might think that Liars were complicit. To the casual observer (who also knows Ezra is “A”), the Liars look pretty guilty.

Do you think Noel knows about Ezra? Sound off in the comments below!
