Bonus: Endless Thrones

If your office is anything like ours here at WBUR, you've probably been listening to your colleagues talk about the return of HBO's "Game of Thrones" every day for the past few weeks. Months even. Or hey, maybe you are one of those people. If that's the case, you'll appreciate this bonus episode even more.

In advance of the Season 8 premiere this Sunday, we talk to a couple of our in-house "GOT" nerds — Katherine Brewer and Caitlin O'Keefe --  and to one of the head moderators of r/gameofthrones to hear some of their fan theories and predictions for the show's final season.

Endless Thread returns officially on May 3 with a special series on vaccines and anti-vaxxers. Stay tuned...
