If fate continues its true course, Marian should be killed indirectly by Regina. Isn’t that the way it goes? Marian was going to be burned to death by Regina’s ruling, but was saved by Emma. Now “Fate” is angry and Marian will die “again” at Regina’s hands.
That is just how I expect it to go. Regina may not be malicious this time, it will probably be an accident, but I see Marian’s days numbered. Poor Roland!
