From the looks of it though, it seems the other teams are only returning to appear in the finale. Worst part? Presumably only the Reality TV pros and Father and Son will be the only eliminated teams with a real role (But only if certain teams stay, if the Sisters are in the finale then Noah will DEFINALLY be a major character in that like Dave was in Pahkitew and if the best friends stay, there's a chance Junior will be (somewhat) important.
