Eowyn's "disguise" - who was fooled by it?

[Saraphim]

I like Eowyn's character, but she strikes me as particularly selfish, especially in her quest for glory and honor. Theoden and Eomer are both riding to battle. If they were both killed in the battle, she would have become Queen of Rohan, correct? But if all three were killed in battle, who would rule Rohan?

Woohoo! Finally, someone agrees with me! I'm sick to death of people getting mad at me because I say Eowyn made a stupid mistake.

But here I am thinking again. If Eowyn hadn't been at the Pellenor Fields, then Merry wouldn't have been there, and then there wouldnt have been anyone who could have potentially destroyed the Witch-King. And then, most likely, the Nazgul would have killed not only Theoden, but Eomer as well.

Anyway. My personal opinion of this topic (apologies for getting away from it), is that Eowyn just stuck around with Riders who weren't from Edoras or would have immediatly recognized her.
