Okay wow apparently it's headcanon time with Ambrose.
Let's point out that he and Silva groomed Honey for years to take her place, okay. Let's start with that. Honey is his, but he's not Honey's. Not yet. Honey hasn't wrapped him up with words of destruction, with power, with mania.
Silva has. Even if he wanted out, he couldn't,not until she's dead. Because there's something intoxicating about her whispers, her words that never cease even during functions- to the point where Sapphire starts to eye them.
He's tangled so deep he doesn't remember what he did without her.
But he's also sufficiently cowed (as cowed as someone as heartless, as unaffected can be), because he's seen what Silva does, knows her capabilities better than most.
So his flippant comments about him being a Seer herder and things similar are just comments.
He's theirs as much as they're his. And make no mistake, he may just be a Normal, but he'd kill/die for them.
