I thought for sure they were going to pick Alex and Jason or Paul from BB19. Obviously, they still could/could've, but I'm hoping they don't. Alex/Jason wouldn't be a terrible thing because they were good at comps, but eh. I suppose Mark and Elena from BB19 is a possibility, especially because they said they want to go on the show. I also think Victor and Nicole (BB18 + BB16/18) could be a strong possibility if they're still dating, especially because of the rumor that at least 1 big brother winner would be included and Nicole won BB18. Can't really think of any other duos from recent seasons that CBS would take from BB though.
