Bishop's Links
The group Bishop worked in had hired Naoise to get information in the past, and Bishop finds him to be rather adorably eccentric. The doll maker fascinates him and is oddly adorable in a way that has Bishop protecting him from the shadows whenever he can manage it. He ultimately takes out the group he worked for in order to look after Naoise more effectively.
Naoise doesn't actually know a lot about Bishop initially, what he does learn he keeps to himself, though, since it's a policy of his not to sell information that could majorly turn the tides in anyone's favor. His neutrality is what keeps him alive, after all...and he'd rather keep Bishop as a friend.
Lancaster is the only past employer in a group setting that Bishop hasn't...removed. They maintain a friendly, professional relationship, often sending work to each other depending on the nature of it.
Lancaster was quite disappointed when Bishop opted to leave his little operation, but the two hold a mutual respect for each other. He does hope for Bishop to return properly one day, but he knows better than to push.
