ME: Look, if you’re going to do what you want, I’m going to do what I want, but you’re not going to like it.

ME: We’ll see about that...

That changes my opinion a bit. I'm sure he had no poisoned treats, but in my head I'd assume he was going to grab the dog. Maybe a citizens arrest, which can go badly.
