Most people had never experienced sharing control of a single body with someone else. Or rather, they might have had their bodies controlled by others, but they could never have cooperated with someone else to control one body. Schiller—or rather, most Symbiote hosts—were experts in this regard.
Perhaps somewhat beyond common sense, Symbiote hosts neither used their Symbiotes as tools nor handed their bodies over to them entirely. Their method of cooperation was somewhat like Cells at Work, or perhaps Overcooked. Only, the kitchen where they cooked was their own body.
It could also be compared to your heart, liver, spleen, lungs, and kidneys suddenly gaining consciousness. They could communicate with you, and you could control them to perform operations humans could not. For instance, you could have a Symbiote adjust your heart rate, accelerate your blood circulation, regulate oxygen supply to your brain, make your skin glow more, or help you grow more hair.
It sounded impressive, but it was not that simple in practice. Growing hair required nutrients, for example. If the host did not consume enough nutrients, the Symbiote could not do it, because it would harm the host. Most Symbiotes would not spend their own energy subsidizing their hosts—unless they loved them too much.
To put it in more commercial terms, the host was the client, and the Symbiote was the contractor. The host made requests, and the Symbiote carried them out. But if a request was unreasonable, they could only refuse.
And if the host gave no command, the Symbiote was basically on standby. The host normally controlled the body on their own.
Under such circumstances, both host and Symbiote had authority to mobilize the body, so one situation could easily arise: their commands conflicted.
The host might think they should raise an arm, but
