Since an AD has spilled the fact that 217 will be episode 18 of the season, I can provide a little background. There WAS a script for 218 but it was rejected by RM at the last minute. An idea that didn't work, apparently. I believe this may have been the screw-up he was alluding to on his blog. To fill out the schedule, 211 is now a two-parter.
I hope you are right about that episode being the screw up, that way we don't have to worry about the episodes he has already done
