Hi there! Since I have a few minutes, I'll take a look at this. As a PG, I look for five things: activity in the community, understanding of the PPC, interesting characters, writing ability, and spelling-punctuation-grammar. So let's take a look.
Activity: Well, I recognise your name, and don't have an immediate 'hey, she's that annoying one' reaction, so I'll tick that one off straight away. ;)
-SPG: Your spelling looks okay to me - I'm sure there are mistakes (everyone has those), but nothing's popping out. Grammar too, though there are some slightly strange phrases - 'When they had visited the PPC the last time' would feel more natural as 'the last time they [had] visited the PPC'. But in general, I'll pass that.
Punctuation you've got a few problems with. You start off with a load of full stops with no spaces after them - you can follow a full stop with one or two spaces, but not none. You also have a lot of missing commas, such as:
*'However>>>,*'As an added note>>>,*'She could see that it was just so precious and wonderful>>>,
And more, but I'm not going to list every single one. As a rule, if you'd pause there while speaking, it needs a comma. 'Well, there's his answer', because out loud, you'd stop after 'well', if only briefly.
You also have a habit of ending quoted speech with a full-stop-and-capital. When the next words outside the quote are a dialogue tag, that should be a comma-and-lower-case. An example:
*'“Hurry up.” She whipered urgently.' should be '"Hurry up," she whispered urgently.'
Of course, you shouldn't do this where the next words aren't a dialogue tag. You didn't, I'm just making the note.
You have one instance of a missing apostrophe (actually, '6:00 o clock in the morning' is entirely strange - it should read either '6:00 in the morning' or, more naturally, 'six o'clock in the morning'. Or '6 am' if you really want. Oh, and PPC time is HQ Standard Time, or HST), and a couple of split words or lost hyphens ('green dresses under over sized lab coats' can either be 'oversized' or 'over-sized', though the former is probably preferable in that case), but in general, apart from the dialogue endings and the commas, pretty good.
Oh, you also have an exclamation point in narration. I'd normally condemn it outright, but it's a pseudo-thought from Murder, so... dunno. It's generally discouraged, anyway.
Understanding of the PPC: Well, it's... hard to tell, really. Nothing in the story after Seyche's first line is really anything to do with the PPC; if you remove 'PPC time', the whole story could take place in any research lab in the multiverse. You don't say anything that indicates you don't understand the PPC, and the things you do describe fit, but... there's not a lot to go on. (Oh, you said 'Division of Mary Sues' where you meant 'Department')
Character: I have no quarrel with the concept of either of your characters. Zombie survivor with violent reactions is reasonable enough, and the idea of being immortal as long as the Seychelles endure is nice enough (though I wonder what you'll do if they ever break up...?). As to specifics...
I'll take Seyche first: you don't describe her personality in the bio, just her physical characteristics. She comes across as fairly pragmatic in the story... how close is that to what you're planning?
Murder: ... well, I'll push the easy one first - you say he reacts violently to being startled, and doesn't like to be surprised, but what you show is him jumping in a non-violent manner after being startled, and not being at all annoyed by Seyche's random screaming. He seems to be more on the 'must protect Seyche' thing than what you wrote - which is also fine as a zombie survivor, but... yeah, doesn't match the profile.
But, bigger problem: you need to show us his actions. Take a look at this:
'Murder sat up a little in his chair and adjusted his glasses. [...] Seyche didn’t seem to share his eagerness. She just nodded once to show that she understood the gestures'
What gestures? Sitting up and adjusting his glasses? Because that's all you've shown us. If you had a character with a voice and never actually wrote out their lines, you'd notice immediately that there was something wrong; this is the same thing.
I'm not saying you should describe his gestures in great detail, but... well, what are we talking about, here? Sign language? A simple 'Murder's hands moved rapidly in reply, conveying his disappointment. It had taken ages...' would work. But not saying anything comes across very strangely.
(Also, why does he use gestures no-one understands? Why not pick one of the standard sign languages, at least? A language ain't much good if you're the only one who speaks it)
Writing in general: I quite like the style of this story. Murder's pseudo-thoughts make it stand out, you play around with the 'tension' of the duck quite well, and you keep the characters physically in the space, rather than letting them turn into talking heads. So okay, sure. (Can you tell this is the one I have difficulty with? Me not flagging up problems = good)
One final point...
Procedure: you haven't exactly hit all the points we ask for in a Permission Request, here. Now, those points are designed to make things easier, not as an arbitrary barrier, so don't think I'm going to say no on that basis. You haven't linked a badfic, but I get the impression you're not planning on taking them into a solo mission right now? So that can be written out. But you also only have one writing sample, and one that leaves me with questions about your PPC knowledge besides...
Essentially, I have three concerns about your writing.
*First, punctuation, which I've covered in detail above.
*Second, PPC knowledge, whether you have any or not, which isn't particularly clear from this.
*Third, Agent Murder: showing his actions, and deciding whether he's violent or not.
And fortunately, I can make one request to answer all of those:
-Please write a second sample. Your carefully-selected prompt is 'Murder and Seyche receive a scientific sample from an agent'. You can use any Free-to-Use character from the Wiki; alternately, if you need one, I can lend you one of my agents (please ask first, though!). (It would probably be Kayleigh, because she has a very... distinct personality) Find someone to beta the sample - I see Iximaz has offered already - and post it to this thread when you're ready; I'll make the call from that. And remember the three things I'm looking for - punctuation, good characterisation/description of Murder, and PPC knowledge.
(Did I say 'a few minutes'? More like 45... oh well, close enough!)
