-- BB USA 21 -- Tommy and Christie knew each other because he knew her partner or something weird like that. Also, he's broadway and she's LGBT and they just had natural theatrics.
-- BB USA 21 -- Holly knew Kat. I forget the logistics here, but the ladies knew each other outside the game.
-- BB 6 & 8 -- Obviously the entire BB6 cast but Carol/Jessica, Dick/Daniele and Joe/Dustin. Biggest nemesis twist BB8 takes the cake with Carol/Jessica having a high school feud over $5.00 that was kiboshed, like, right away. I know loads of other seasons like BB4, BB5, BB7, BB9, BB13, BB14 etc have pre-existing relations, but I had to mention this one for the five dolla thing.
-- Survivor Samoa -- Laura M. and Brett. They attend the same church. Go figure! Small world.
-- Survivor Gabon -- Crystal Cox (MASSIVE CRYSTAL) and Dr. Marcus had a friend of a friend relation that prompted Ms. Cox to blindside Marcus. She went back on her word, because duh, but only after the he knows her cousin connection made him let his guard down.
-- Survivor Gabon/Pygmy Island -- Apparently Randy and Susie (SUSIEEE) are/were pygmy islanders which is a whole other kind of reality fandom niche group. Like Survivor Sucks or Tengaged in a way... only nicer, likely due to being fine tuned by a moral compass and a user code of conduct that Sucks lacks.
-- Big Brother Canada 2 -- Kenny and Allison. They had convos on the feeds about knowing each other from their hometown and such, it was spectacular because it didn't really help them besides securing Allison to go down with the first five as jurors.
