John Bradley may have dropped the bomb in the first episode of "Game of Thrones" Season 7 which aired last Sunday. Midway of the hour-long broadcast, Sam Tarly appeared in a montage of his daily routine at the Citadel where he works to become a master.

Sam in 'Game of Thrones' season 7 premiere

Following his conversation with Archmaester Ebrose (Jim Broadbent), Sam found the courage to enter the restricted area of Citadel's library in hopes to find the answers about the White Walkers. Bradley told TV Line that his character requested to be sent at the Citadel for an important reason.

"He wants to go to the Citadel and work, and find knowledge that he can apply that’s going to change the course of things for everybody," the actor explained.

It can be recalled that Sam personally asked Jon Snow to send him to the Citadel where he can help the King of the North win the war.

After he had broken into the restricted section of the library, Sam was seen looking through a certain book where he discovered the mountain of dragon glass located under Dragonstone. But before he found that page, Bradley's character lingered on a certain leaf which showed Little Finger's dagger.

Theory on Little Finger's death

The same dagger was seen in Arya Stark's promotional photos for "Game of Thrones" Season 7.

This has led the fans to speculate whether Maisie Williams' character will kill Little Finger (Aidan Gillen) at some point in the current installment. This, however, will remain a fan theory until the seventh season concludes on August 27.

Meanwhile, Bradley revealed that he was particularly asked to stay on that page to give emphasis on the familiar dagger we've seen in the first season of the HBO series.

"Make sure we get a good shot of this page before you turn the page over,” Bradley told The Huffington Post.

He went on to reveal that the particular scene has something to do with the overall storyline of the show. "No matter how spread out they feel sometimes, they are a lot of the same storyline and in the equation...and if you think you saw something you probably did see something," he explained.

Although viewers may think of that scene as irrelevant or insignificant, Bradley assured that all things are part of D.B. Weiss and David Benioff's plan. Bradley, who is the main character of the HBO series, said all actors are doing their best to witness the fruition of their hard work. Also, the actor did not miss the opportunity to apologize to the "Game of Thrones" viewers for the gross montage of his life inside the Citadel.
