>>87756836Cerber is NOT a leech, because that implies a parasitic relationship in which the parasite benefits and the host is harmed. However, in this case, the host is neither harmed nor helped, so the relationship is one of commensalism.
The definition of a leech would be Anny, who benefits from all the clout Neuro gives her yet harms her development by not delivering the model.
A mutual relationship would be with Ellie, where she benefits from the clout Neuro gives her and, in return, gives back by building and showcasing Neurodog's development.
