One possibility is that MK could delay Team RWBY's meetup by having Yang encounter something before she gets to Mistral and having the airship Weiss is in have a crash landing for whatever reason.

I still think Blake will be the last member of Team RWBY to meet up with the rest of the team, especially since she still has not left Menagerie.
