"How would one escape?"

I don't think he has the vocabulary for that yet, Rúmil says. 

How would one escape?

I don't know, I've never been to Mandos. But if it's been thirty thousand years he'll have had time to try lots of things. There's technically no reason you can't enchant the planet's bedrock, if you wanted to and had, well, thirty thousand years to spend on doing it, your fidelity would have to be amazing...

Can you think of any way to check if your alt's still in Mandos?

We could try talking to him with the earbuds! Bella?

Mandos might notice.

Oh. 

We could try talking to this world's Rúmil? He's probably not in Mandos.

He's probably not, but Idaia and Imliss never met him and I'm not sure why or what that means.

Nerdanel?

Did you ever meet your Nerdanel?

Yyyyyeah but she, uh, didn't part from Feanaro on the best terms. Didn't earbuds work via closing osanwe-distance? Osanwe doesn't work on the dead, wouldn't that only work if they were outside Mandos somehow?

Yeah, that seems likely, lemme look at my notes... Rummage.

"Bella is looking for her notes," she tells Feanaro helpfully in English.

Yeah, earwires don't work on dead people. But even if we don't know why Rúmil wasn't around by the time you met your version he still wasn't and that might not have any happier history than Nerdanel? I don't know.

Could still try it on Feanaro, it probably won't work but unless I'm wrong it's a cheap test.

Yeah, it's safe to try on anyone who's probably dead and if not dead is friendly.

I'm definitely going to be friendly.

To be fair, we don't know what happened after I died, you might not react well to a stranger osanweing you from nowhere.

...Maybe if it's in an unfamiliar language. He wouldn't know Pax.

True.

I'd definitely be excited about learning Pax, no matter what happened after you died.

So Bella should make the call.

Or Rúmil or me, we both speak Pax!

Or Imliss or me, even, since although we don't know Pax we're not strangers.
