So, the entire main cast (except Zelena) was seen filming on the same lake that the Fury attacked Robin. A bunch of people (at least 10) were seen wearing Grim Reaper's clothes (like the Charon's). And one really random thing: There was a female version of Rumple there. She had the same hair and makeup, but darker clothes.
