It should be "Euromaidan" and not "Euromadian".

PC

On Returning
This is a pleaasant little interlude, although there was one things about it that I do admit to being confused about even after several read-throughs. Are the members of the angry mob supposed to be other PPC agents? It seems to be taking place in the PPC judging from all the references to impossible achitecture and various departments, but the mob members are just a generic formless mass. It might have been nice to detail them up at least a little with phrases like "a sea of furious black-clad figures" or "she narrowly avoided the grasps of several [department] agents" or what have you.

On Boorman
The Boorman script was not something I was previously familiar with, so it was interesting to get a bit of insight into it. I also really like how Kyaris was called into the mission for a consult. That's something I'd actually like to see a bit more, the pop-in consultation/assist. It's something that could potentially lend itself to good bits.

On End of the Beginning: Euromadian
I liked this piece, although I will say I can see how some people (like Ekyl did down below) would not given the current events angle on it. The PPC is (typically) somewhat light and humorous, whereas the conflict in Ukraine is anything but. I personally enjoyed the look into Nyx's backstory and I liked the interaction between her and Tango. I don't believe the internal monologue would have worked in this case. Plus, as you said in your reply to Ekyl, a story where an agent's partner helps them heal and carry on from their issues is far more interesting (both plot and character-wise) than just a struggle inside a person's own head.

On Getting Some Exorcise
This was probably my favorite, and I'm not just saying that because of the little nod to Xericka (although it certainly didn't hurt). This was just plain fun. Each exorcism scene was interesting and had some good humorous bits in them. I liked seeing your agents being basically corralled into become test subjects for the DBS. I think my only major complaint was that it wasn't quite clear what was going on in the Pokemon-themed scene. It took me couple of read-throughs to understand what Sandra and Freckles had actually done.

All in all, some kudos-worthy additions to PPC lore.

I just got up and gave these a read-through, so a lot of these might just be initial impressions that I'll either not entirely agree with upon further reflection or find I wish to elaborate on, but hey, I need to get my critic muscles moving again somehow, and people've been saying there needs to be more concrit around here, so here we go. Starting bottom up because a) I feel like it and b) the new stuff is at the end of the plug:

I might be biased against the Bad Slash one because now I have to completely start from scratch on one of my missions. I can't even keep one of the main agents' names or use LOTR. Grrrr. ;) But seriously, I like the use of nonconventional exorcism methods/ones more tied to the actual canon, it's an interesting touch and I'm a little tired of all exorcisms consisting of nothing but hitting things with books and screaming "Avaunt" over and over. It's nice to see other ways of doing things, even if I'm beaten to writing them. :P

Expelling a wraith from Arda through music and dance is an especially nice touch. The QAL pointing out Freckles is an odd nickname is pretty neat too - I'm not sure I like them being established as "among the SO’s most notorious Assassins" right out the gate though. I've certainly never seen these agents before, but I could be wrong (the wiki doesn't say anything about them...), and either way that feels like a title that needs to be earned, not simply slapped on the second somebody shows up - especially with the market so competitive on that ground. It turns out to have nothing to do with the rest of the mission so I'm not sure there's a point to having it - you could do with just going right to the QAL being surprised they want Bad Slash, specifically. Hieronymus went into the whole Patronus thing so I won't bother commenting on that, though I'm curious about why these all seem to be crossovers. I do sort of wish these had been established as a way to do it as opposed to the way, as well, if nothing else because it's kind of constraining to future authors.

I'm of two minds about the Nyx one, though part of that might be me being preoccupied by the fact we're looking at the start of WW3. It's hard to be amused by a story around something that's going to end with us all being blown back to the Bronze Age at best. I like the idea of agents actually reacting to stuff going on back home, though, it's something that doesn't come up a lot and really helps HQ feel more alive - these agents came from somewhere after all. I also think this piece could've been better served as just Nyx on her own - maybe that's personal preference but I didn't really feel like Tango added much except her own commentary, a lot of which felt like repeating things Nyx and the reader already know. If this were Nyx alone with her thoughts it might've been more effective. In spirit of full disclosure, though, I've never particularly liked Nyx and thus my enjoyment of this was a little limited between that and the whole World War Three thing.

Boorman is interesting and I don't have much to pick at. While it feels like a bit of a needless jab at a project that ended up never happening, I do like the idea of accidentally crossing from a fic written around Boorman's script to Boorman's script itself, as well as stuff like the recurring DAVD flashpatch problem (though in places it seems to imply DAVD simply doesn't have one). I also find Rile X getting dragged along to serve as Mortic's partner amusing. Mortic's felt kind of inconsistently written in some past things he's been in, but here he works well enough.

"I need a partner," Mortic said bluntly.
Returning... I'm pretty neutral on, I must admit. Not a lot earth shaking here, but also nothing I'd say is super bad, though I think prequel jokes are a little passé by now - next year even ROTS will have been a decade ago. And just because it's unclear, which lobby is being referred to re: potted plants?

Your description of the Patronus charm is not exactly how the books describe it. Did you get it from the movies? Relevant quotes:

“But the Dementor didn't move, so Lupin muttered something, and a silvery thing shot out of his wand at it ...” (PA 5)

“... and then a huge, silver shadow came bursting out of the end of Harry's wand, to hover between him and the Dementor ...” (PA 12)

“Something silver white, something enormous, erupted from the end of his wand.” (PA 13)

"A thin wisp of silver escaped his wand and hovered like mist before him." (PA 20)

"And out of the end of his wand burst, not a shapeless cloud of mist, but a blinding, dazzling silver animal." (PA 21)

"He raised his wand into the air and pointed it into the direction of Hagrid's cabin. Harry saw something silvery dart out of it and streak away through the trees like a ghostly bird." (GF 28, Dumbledore sends a message)

"A silver stag erupted from the end of Harry's wand and galloped towards the Dementor ..." (GF 31)

"An enormous silver stag erupted from the tip of Harry's wand ..." (OP 1)

"His silver stag erupted from the end of his wand and cantered the length of the Hall." (OP 31)

"The silver stag soared from the tip of Harry's wand and leapt towards the Dementors ..." (DH 13)

"The silver stag burst from his wand and charged ..." (DH 28)

"There was a silver spark, then a wavering light, and then, with the greatest effort it had ever cost him, the stag burst from the end of Harry's wand." (DH 32)

"From the tip of his wand burst the silver doe ..." (DH 33)

HG

That was where I first heard of the "pin-headed" azdarchid model, and it's got a few informative articles about azdarchids in general (the one about speculative terrestrial flightless clades was my favorite). And my guess is the azdarchid could've come from the Land Before Time continuum, since flyers there are usually friendly.

...Dammit, now I feel pedantic about pteranodontid taxonomy, anatomy, etc. I was going to express that in the first part of my first mission, but the second part is probably a better opportunity for that. There's a scene from the badfic I'm sporking in the mission involving the Pteranodon attack from Jurassic Park III, except with different characters involved.
