They watched without comment as she turned off her laptop and listened to a soundtrack with headphones from the show ...
So Karianne got the headphones from the show? How did she do this? (Try alternate word orders like "listened with headphones to a soundtrack" or "a soundtrack from the show with headphones". But I’m not sure whether this sentence can really be rescued without changing some words and putting in some punctuation.)

What is a Covenant Shrub? (You probably meant the "Convenient Shrub" mentioned earlier.)

Who is Natalie eyes? A mini-agent? (Should be "Natalie’s eyes".)

One question: Who's "him"? Generally "Upstairs" is an umbrella term for the Flowers That Be as a whole...

I hate those Time-Lady-with-a-speshul-connection-to-the-Doctor Sues. Good to see this one killed off.

It might've been nice if Natalie had more of a reaction to finding herself sitting on top of the Doctor. But apart from that, it was great fun. I loved it.

I prefer the classic series to the new overall, but this...

BTW, what's the canon status of the BBC continuity that airs when Ace turns the Smiths' TV on in Remembrance of the Daleks?

I love that duo! :D

Oh, I'm so glad that Sue's dead. Seriously, teaching River 'spoilers'? Not cool!

I really enjoyed the little fangirl Natalie experienced at the beginning :D Also, Za'kiir's humming was nice - I wanna hear his cover of Ragnar the Red.

I always enjoy non-human agents, and Za'kiir is pleasant - though I admit to knowing absolutely nothing about Skyrim other than it has at least one Khajiit living in it. =]

A solid and enjoyable mission, especially considering it's a pretty early effort. One thing stood out though:-

'The C-CAD's screen promptly went bank'
Should be blank. Unless the C-CAD has nipped up to take a bit of cash out while we weren't looking. =]
