Will Missandei and Varys be on a sinking ship?

[DaemarysStormborn]

Based on the joke that Missandei told in episode 8 of season 6 about two translators on a sinking ship, do you think that she and Varys (or Melisandre?) will be on a sinking ship soon?  Perhaps when Daenerys finds out about Euron's attack, she will send two people to Dorne again to continue with her original plan of getting people from Dorne on ships to King's Landing.  Maybe that scene from episode 8 and the joke that Missandei tells are foreshadowing?
