At this point, I think "Luggage" is more appropriate than "Radar."

is Noah a hamper?

Hey come on, Catz, the catdroid is also carrying an injured party member! Very valuable ability, don't underestimate that!

In the 5th panel, Gaston is saying "tellinS", but it should be "tellinG", right?
(Not sure the comment section is the place to report typos though...)

I like Rolly Polly as a nickname

I think "Tellins" might not be a typo, just a Gaston way of speakin'.

I think Noah is at least partially conscious, from the moment before entering maze. He says nothing because there is no reason for him to do so. The radar works fine thanks to Ciel.
At this point, Noah doesn't want or need to contribute more. If he woke up for good, he might have to walk, run, or use magic actively. All this is tiring. And thats fine. it's good for him to rest, he deseve it. He'll wake up when he needs to, maybe if he thinks he has to activly hide knowledge about Ciel from Nail or save the party in some way.

@Luke I might agree, except if Noah doesn't close his mouth or eyes soon my dude is going to be ABOMINABLY dry. "My eyeballs have gotten crispy" kind of vibes. Don't think any amount of rest and not-having-to-do-shit is worth that, so my bet is this is still unintentiobal, and Noah will be miserable when he's awake again.

Hopd they eventually have a Eureka moment and wonder why the Catdroid even has signal from Catz in the first place

@ Luke & Woodledude: Even in the case where Noah is assumed to be conscious he still wouldn't be able to speak. His jaw has a giant metal trap on it still, after all.

Oh, and I agree that Noah's still unconscious. I'm fairly certain that his eyes being so pale is a part of what shows whether or not Noah is conscious or not. When he was conscious his eyes were a bit darker than they were in the last page. This page is an exception, because the one Panel we see Noah's face, his eyes are covered by a word balloon.

Actually, I think Noel may have an option here. He may not have seen it directly, but he can claim to be speaking to Noah foalting spirit body.
Tall claim, I know, but still a semi-plausible option to keep things under wraps.
Then again with everything else going on right now...
