Parasite may also reflect Taylor, or even more darkly, Imp. Taylor literally was a parasite to the team, and Bitch still thought so. Imp isn’t getting on well with the team leadership, due to being a bickering, attention-starved sibling. Finally, we know of some parasites to society, who are a symbiotic band of muderhobos.
Hm, yeah, good points. I’m not sure about the Imp point, because while she might not be all that good at being subordinate to Brian, she seems to be a benefit to the team overall, but Taylor was intending to be a parasite for information.
