"Yes. It's another Realm that I hadn't heard of—how did you hear about it? I don't know what a Silmarillion is but if it's related to a Silmaril then I have encountered those."

"You what—they were lost forever—

"The Silmarillion's a book. About the history of the Elves in the First Age. I knew it—and loved it—as a work of fiction. It's, uh, interesting to find out it's not." (Mostly exciting, but it also contains a lot of horrible suffering that she would prefer not have happened to actual people.) 

"I'm surprised that this distracted you from the time travel."

"Oh, the combination is even more exciting—I mean, elves are immortal, so I could technically still hope to meet one, but Fëanor, uh, wasn't—"

"We're hanging out at his house right now. Sometime way back in the past—I don't know how far precisely but it must be a long way since there's no sun—"

dhjsjgkhsj.aghdjlk'anwklsnklnsks.ngkns,mdgnsm, is the only possible response she can come up with to that.

"Okay. You're going to have to back up a bit. What, exactly, is happening in the future?"

"Someone used the Infinity Stones to murder half the universe. We're going to prevent it here—probably by taking your Reality Stone and not giving it back—but we need the full set of six to undo it, and right now Thanos still has the ones that belong to our timeline. We're using way-past Valinor as a safe base of operations."

Aaaaaaah half the universe—

"Alright I'm going to trust you to fix that since it is way out of my league of problems to deal with. But if you're still gonna show me the time travel, I want to see the Two Trees, not the universe that's half dead."

"Right."

Then he turns to Vanyel, Leareth, and Savil. "Apologies for that—I'm not sure how much you could understand. This is my girlfriend Jane—" :Well, ex-girlfriend, in our timeline, but I haven't mentioned that since it's kind of awkward: "She apparently knows of Valinor and elves from a book that she previously believed to be fiction, and would like to see them, so she'll be coming back with us, I suppose."

"At any rate, you wanted to see Asgard, so let's go somewhere other than the hospital. Jane, are you ready—?"

"I'm feeling much better now that a magic artifact is no longer trying to eat my arm!"

"Alright, let's go. Keep in mind that humans aren't technically allowed here, but there won't be any trouble as long as you don't make any."

He takes them to a window with a view of the city. "Any particular thing you'd like to see more closely?"
