Season 25 of Big Brother is full of twists, surprise houseguests, showmances, and backdoors. In other words, it's the stuff that the show is made of, even if some viewers might prefer a more straightforward season. But the last surprise of the season might fall on finale night when we see who wins Big Brother 25.

Catch Big Brother on Sundays at 10 p.m. EST, Tuesdays at 8 p.m. EST, and Thursdays at 9 p.m. EST on CBS.
