Does he say "I'll be your huckleberry"?

Excuse me, but could you please clarify something for me? In the context you've mentioned, is there a specific individual who is being referred to when the phrase "I'll be your huckleberry" is uttered? And if so, is this a direct quote from that person, or is it a paraphrase or interpretation of their sentiment? Additionally, could you elaborate on the significance of this phrase and why it's being brought up in the conversation? I'm genuinely curious to understand the context and meaning behind this statement.
