Riley:  We 've been tear - assing through every jungle from Paraguay up , taking out nests . As soon as we put one Suvolte down , a dozen take its place . They 're breeders , Buffy . One turns into _ ten _ , ten becomes a hundred . This gets out of hand and there 's a war with humans ? Humans are gon na lose .
Buffy: So they 're like really mean tribbles . Sorry , I 've been dealing with these , these geeks . It's - it 's a whole thing .
