Hmmm, Kail's
important? Truly, I never could have seen this coming
Of course, the real question is why, and how.
I thought the Mordred-Morrigan dialogue worked fair. Ellie's little quips like "Mordred? You have got to be kidding me." made the chapter enjoyable. It moved quickly, which may or may not be a good thing (see below!)
Main thing I had a problem with was why Ellie wanted to save that man. It wasn't entirely clear to me, other than Ellie just not wanting to kill anyone, I suppose.
For a larger issue, I don't seem grounded in this world at all. This could be a symptom of me not reading this story for a while, but where are they? Last I remember they were in a town, and now they are in somewhere... else? How large is Morrigan and Mordred's dominion? I don't know. It just felt like Morrigan wasn't immediately important, besides being important in a familial way, when she's actually the Queen. The scene moved so fast I didn't get a reaction from Ellie to the setting itself, like reverence or something from being in front of Morrigan. I don't know if that makes any sense.
Other questions: How does Morrigan know about other worlds? Right now I can buy that she's really powerful, but you better explain how a person from one world can know so much of another. Also, if Morrigan is Fae, and Mordred's father is implied to be not-Fae, wouldn't that make Mordred half-Fae?
EDIT: One line-level thing I forgot. You really like using "then" to start sentences. In small doses it's fair game, but it's kind of getting repetitive.
