So I've been doing a little bit of research on BBUSA and CAN and I've found out that there were some alternate housemates that got replaced last minute, or there were housemates that replaced someone else. I've also seen some occasions where a housemate has been cast on an earlier season, but they got cut but were cast a few years later again. So I was just wondering, are there any known alternate housemates or housemates cut from the casts?
