'Pretty Little Liars' theory: Lucas is Uber A, revelation to happen at series' final episode

This upcoming return of “Pretty Little Liars” to is going to be bitter sweet, because while fans will finally learn who Uber A is, it also means that the popular mystery-drama is coming to an end. But during the show's break, fans have been entertaining themselves with their own theories about who the notorious Liars stalker is.

A recent YouTube video that has gained popularity is pining Lucas as A. The video, which was posted by G_xoxo and can be watched here, points out several reasons why Lucas could be the series’ main antagonist. These clues include his appearances at the most convenient times, the fact that he was a minion of Mona and his interest in pyromania.

And while these reasons shape the theory as a likely situation, it still begs to ask why Lucas would be harboring such hatred for the “Pretty Little Liars” girls. The same video eludes to the idea that Lucas is Spencer’s twin and is therefore also the younger sibling of Charlotte. Furthermore, Alison was slightly horrible to him in high school and the Liars hardly did anything to stop her from being so. Could everything that has happened to Spencer, Aria, Hanna, Emily and Alison be a result from what could be the biggest grudge ever?

The answer will not be revealed until the final episode of “Pretty Little Liars.” Season 7B is still a few weeks away, but there are certain details about the same that have already been shared with the public. Creator Marlene King has confirmed that the final episode will be longer than normal and will likely be a two hour special event. More importantly, however, Pop Sugar has reported that all questions will be answered before the end credits roll.

“I’m excited for fans to finally have all of their questions answered,” the publication quoted her saying. “And I believe they will be satisfied with the wild ride that is our last ten episodes.” The publication went on to state that a wedding will be part of the final episode and that the very final shot will include all five girls. And while these are good things, fans should also be ready to say goodbye to one the characters, as a death is likely to take part as well.

“Pretty Little Liars” season 7B begins on April 18 in the United States. US audiences can catch the same on Freeform, while Australian audiences can watch the series on Fox8.
