Well we'll see how this epic conclusion between her and a single guinea pig shall go. I'm fine with either one winning. On one hand it would be nice to see her rewarded for her clever gambit. On the other hand there's sequel baiting and the dark humor of a human being defeated by a loan Guinea pig.
I personally think a good sequel could be that the lone guinea pig survivor manages to pretend to be a normal guinea pig, observing humans, gaining intelligence, and regaining it's strength all the while being a pet stuck in a cage. Everyone thinks Nillie killed them all off so that's how this guinea pig went under the radar. Nillie's brother vows revenge for her death, being the only one who believes that a guinea pig had managed to escape the battle but having no proof. He has an irrational hatred of all guinea pig kind now.
