Im pretty sure Alex has said she actually applied for The Amazing Race with her BF , and they approached her about BBOTT instead . And Morgan said earlier today that they both didn ' t know each other applied and one of the casting people told her do you know that your sister applied ? And she said there ' s no way she did and was surprised . Alex had told Morgan to apply for BB many times before but she never did until now . Maybe Alex thought Morgan just had a better chance at getting cast ? Not sure . And then they were told the entire time that they were each other ' s alternate and only one would make it . They were asked about each other in their intros , but Alex and Morgan both said that they were asked soo many questions and they were told sooo many times that they were each other ' s alternates and would absolutely not be on together , so they just believed it and didn ' t know for sure until Alex walked into the house . I ' m not sure what Alex can say , but maybe she can correct where I ' m wrong . this is just based off what I ' ve heard them say on feeds
