[Gwathagor]

I'll lay my cards on the table.

I think that Fea has lied about Eomer, and that Eomer is playing along. I also think that he wisely claimed not to have protected you, Nogrod, in order that he not contradict the real Ranger. And, suddenly, the idea of two Rangers is introduced and the real Ranger is no longer able to prove Eomer's guilt by a counter-reveal. This is how I see the situation, and it's diabolical.
