nice bit of headcanon there.

And everyone is right regarding not seeing Marian's OT death. However, the events leading up to her capture by the EQ did not change (Emma did not interfere with the timeline until after seeing Marian in the Queen's custody), and it can be assumed that Marian's ultimate OT death was at the hands of Regina. So the real question would be how was Marian captured by Regina, and what part did Robin have in the events leading up to her capture that led him to blame himself?

Of course (and this is probably off topic), it is possible that the Huntsman (in the original timeline) came across Marian in Regina's dungeon, and helped her escape, allowing her to return to Robin, and the events that led to her death occurred later. But that line of reasoning leaves some extremely large plot holes for which there is no explanation. I'll stick to the story that Robin did someting that directly or indirectly led to Marian's ultimate capture by Regina.
