Samuel is… thoughtful, or at least that’s what it looks like. It’s hard to determine what exactly he’s feeling, probably because of his expressionless, metallic face. But he’s clearly interested in something, as shown by the way he’s so intently looking at the little being that he’s placed inside of a glass cage. Said being looks like a mere child, and a human one, but he’s learned through years of experience that he can’t trust anyone just because they look innocent. And even less this particular someone, who has been seen with the Slayer himself on multiple occasions.
“What exactly is your relationship with… Him?” He eventually asks, gently knocking on the glass of the cage to get the attention of his small captive. He doesn’t plan on hurting them, not at all, but he’ll have to use some persuasion to get the information he wants. He’s not a villain, but maybe he’ll be seen as one by the kid after he literally teleported the Slayer to who-knows-where. It was for the sake of human progress, and both him and his employees (or what is left of them) know that, but some people may not understand so easily.
He doesn’t know that the kid is the Slayer’s, of course, but he has his suspicions, even if he can’t physically imagine the Marine as a… Father.
“Were you helping him in any way? Was he training you, perhaps? I am positive that you are related to him in some way, but I still need to determine how.”
Samuel waits for an answer, but he doesn’t immediately receive one. He decides that he needs to explain himself and his motives a bit more, so as to not be unreasonably hated by a literal child. He doesn’t know why he cares, but he does.
“He hasn’t been hurt, if that’s what you’re worried about. I can’t hurt him. I can’t kill him.”
