Here, have a triple chocolate cupcake (chocolate with chocolate chips and chocolate icing)!

Congratulations! Hype! Confetti!

So I like nearly everything I'm seeing here. There's a clear sense of humor, I can tell you're having fun writing these characters in goofy situations, and I think they'll make an entertaining team to read about. On the strength of that impression alone, I'm happy to say Permission Granted!

However, caveat: make sure to read up more on other PPC works to be sure you understand the setting. Related to this, be sure to make it clear what your setting is in your writing. The second piece had me a little confused at first, since it starts off talking about how much Marie likes World One and its technology. It goes on to say she's in her RC, but I still had to give it another read to be sure she was supposed to be in Headquarters—which, for the record, is not in World One. First impressions matter!

Also, I don't see why an air duct would reliably get Marie from her RC to the World Tree in (I presume) the Magnus Chase universe and a portal wouldn't. I can only guess that there must be a plothole in that duct... but portals are stabilized plotholes. That should work better than a random, unstable plothole. If it leads to Comedic Shenanigans anyway, so much the better!

There was something else, what was it... Ah, paragraphing. In general, be sure to start a new paragraph any time you change characters. This paragraph is a great example:

> “Alfson it is, then. Mine’s Cheon.” Cheon - or as we will call her, Marie - raised a cocky eyebrow. Ollie’s smile went from cordial to merely pleasant, though his proffered hand showed no sign of wavering.

The two characters are in a dialogue here, so dialogue rules apply even though Ollie's response is non-verbal. It needs a new paragraph.

Same deal here:

> “OllieAlfsonPee-Pee-SeePartner says, i am stuck in the Tree.” Tongue poking out of the corner of her mouth, Marie tapped out a response.

Ollie's message and Marie's reaction should be separate paragraphs.

And a last, very nitpicky point: make sure your punctuation is consistent. You've got spaced hyphens instead of dashes in one line and a pair of hyphens instead of a dash in another. Since you're using Gdocs, you can get proper n-dashes (typically – spaced) or m-dashes (typically—not spaced), depending on which style you choose, by going into the Special Characters menu. You can also add an auto-replace function so it changes what you'd normally type into the style of dash you want. It's nice! ^_^

That fic looks quite silly. You could probably find something worse, but I reckon it'll make a fun mission anyway. Plot tension? What's that? {X D

With that, go forth, young writer, and spork!
