In the ballad, Robin Hood is Marian’s childhood sweetheart. Upon hearing that Robin has been outlawed, Marian dresses herself as a page boy and heads towards Sherwood Forest. She encountered Robin, who is also disguise, and nether recognized each other. They fight and fight. Both a fine match until the standstill. Then Robin invites this disguised stranger to join the merry men, they both realize their true identities. Robin and Marian were married a short time later.
Sometimes Marian is an active member of the band, a skilled archer and fighter. Other times, her true affiliations remain hidden and Marian stays in Nottingham, spying on the sheriff’s plans. I would more say that Jonas Armstrong is not my idea of a Robin Hood figure. He remains me of a teenage guy, slouchy pants and all. In the few pics and Youtupe videos I have seen I haven't really been impressed.
....just my point of view. =)
