Tyson works better as part of a team, rather than as part of a group.
He doesn’t have the same level of focus on a patrol with another soldier, both with the task of completing that patrol whilst watching for enemies, compared to going off as a team with Sebastian Moran, as sniper and spotter both with separate but complementary roles.
That doesn’t mean that Tyson can’t be very effective when taking part in combined, singular efforts, but he does much better when each person is a cog in a bigger mechanism.
It helps him focus on his own task without worrying about carrying the weight of someone else and gives him better perspective on the strengths of the employees he’s working with. It’s easier to spot the weak link and fix the issue before it becomes a problem when there is a link to point at, rather than one action spread across several people.
When people are given an individual goal as part of a team effort, Tyson finds it much easier to support another employee/pet to overcome their difficulties and understand where attention needs to be given. He knows that people are disposable within the web, but Tyson wants to give people the best possible chance of remaining useless; remaining alive.
