I'm watching 'Into The Badlands' (Season 3, episode 7, timestamp: 21:00--) and I came across a sentence I've never heard before. I would like to know its meaning.
Background: Sunny went to find the other survivor of the massacre happened in the boat when Sunny was a child. Finally, he found the place of that old man. The conversation between them is below: Sunny: You're a hard man to find. Old man: Are you here to kill me? Sunny: The River King sent me. I'm here to talk. Old man: Suit yourself. (Offers him a drink but Sunny denies). More for me then. Sunny: The River King says you were the only survivor of a massacre. Old man: Well, there goes my buzz. What's it to you? Sunny: I was also on that boat. Old man: You..... you were the boy. You were the one they were after.
I think it's enough context. Could you please tell me the meaning of emboldened phrase? Thank you.
