...Is it bad that Rina's starting to scare me a little now? Cause she is. I hope she gets some help soon. (The joke about Rina's guinea pig was great, by the way, well done.)

Some things I noticed:
“...hiding from the Silence on the streets of New York.” Rina recited.
That period after "New York" should be a comma.

“No, seriously, who the flying ...nuggets is Victoria?”
According to Wikipedia, Victoria (Waterfield) was a companion during the Second Doctor era. She first appears in "The Evil of the Daleks," where her scientist dad's time travel experiments attracted Dalek notice. What I don't understand is how a Suethor knows about Susan (who actually was the Doctor's granddaughter) but not about any other Classic Who companions. *shrugs*

His partner’s behavior was just going to have to wait.
Abrupt ending is abrupt. I assume there's a part two forthcoming?

Can't wait to read more, though. Rina is being scary. Very, very scary.

Rina... dood... take a chill pill. In fact, take ten of them. o.o

Rina: I WOULD, but I'm FRELLING ALLERGIC, argleblargle@#$%!@#$%

Oh... okay... right... sorry. I'll just. Um. >.> *sidles away*

For what it's worth, I don't think she's going particularly glittery here. The TARDIS-flying is perfectly well justified, IMO. As for the premature killing, that's less glittery, more flamethrower-y.

... Five days until LMM, eh?

Good boy, Zebbie! Have a poffin! :3

"Rina eyeballed Zeb for a moment. “You humans?” she said finally."

Rina's starting to experience Time Lord superiority? 0.0

And of course grandchildren. Susan and Victoria.
