Spoilers for Game of Thrones, season 7 below.If you watched that scene in the Game of Thrones premiere and wondered why the maester refused to let Sam into the restricted section of the library, maybe it's because he remembered Tom Riddle.HboThat citadel maester, making his series premiere, is played by Jim Broadbent. You might remember him as Professor Slughorn in Harry Potter. In fact, here's Broadbent talking to Tom Riddle about the restricted area of the Hogwarts library.https://www.youtube.com/watch?time_continue=15&v=buJPwD5nW1gThe situation's different—the future Lord Voldemort wanted clarification on something he had already read in an off-limits book. Sam Tarwell wanted a permission slip to go read about White Walkers. He ended up disobeying orders and sneaking into that part of the library, anyway.Lol at Sam asking Professor Slughorn for access to the restricted section without bringing him crystallized pineapple. Idiot #GameOfThrones— Mason (@MasonJar38) July 17, 2017 So both bad boys ended up in the restricted area of the library and talking to Jim Broadwell about it. That's more than enough to send fans into a code red, "my-two-favorite-fantasies are crossing over" frenzy.Sam asks Professor Slughorn if he can get a note of permission to go into the restricted section of the library. #GameOfThones— Sam⁷⚡️ (@hogwartsahoy) July 17, 2017 SAM IS TALKING TO SLUGHORN ABOUT THE RESTRICTED SECTION #GameOfThones— O&T Eternal Champ of the Week (@AUSquid) July 17, 2017 https://twitter.com/llamadetective/status/886762508954062848This Citadel restricted section Sam scene with Jim Broadbent seems oddly familiar... #Slughorn #TomRiddle #Horcruxes #GameOfThrones pic.twitter.com/ZeGwxSmcRd— Micah Tannenbaum (@mjtbaum) July 17, 2017 Sam is trying to get permission to go into the Restricted Section from Professor Slughorn.
