LAST EDITED ON 06-09-13 AT 08:34 PM (EST)With the Blood v Water theme, if it is indeed that blood are blood relatives and water are not blood related, Candice and hubby (water) wouldn't work as a sub for RC and father (blood). The theme really complicates up the alternates, it can't simply be older male, younger male, older female, younger female. They may have flown out a tribeworth or more of alternates.
male/male, blood related
male/male, not blood related
female/female, blood related
male/female, blood related
male/female, not blood related
Throw in a match on a race basis, matches for approximate age groups, they could have had two tribeworth of alternates. That's a lot of people interrupting their lives just to get a free quick trip to the Phillipines then just go back home.
