Best Friend
Killer's closest friend. He doesn't know quite why it happened, or what pushed him over the edge. He does know something about the relationship with
Girlfriend, and suspects that that was involved, but he also knows that
Killer was getting moodier before that broke off. There were hints that something was going on that Seamus couldn't talk about, but had something to do with the company's projects. Beyond that, though, he's mystified.
This may well be the same character as
Rescuer, which would inject some terrible pathos.
