Word coming down today that the issue of Icabod's clothes is going to be addressed.
We had the Roanoke episode in the UK last night, and Abbie did mention that he could use a change. (they must stink by now!)
Not as dodgy an episode as I expected from the comments here- I dunno why the colonists spoke Middle English when even Ichabod himself dated that language to centuries before them, but so long as he mentioned that fact, then I can hold out hope that it's a deliberate mystery.
Oddly, neither Lesley nor myself needed subtitles for the adults speaking it, but did need them for the kid's lines...
