It's not a date (unless the female BH makes it one). He'll offer to teach the male too. All he's trying to do is help you learn the Mandalorian ways, speaking the language is one of the resol'nare after all, and you can turn down his offer anyway.
This isn't true, you can romance him even if you decide to turn down Mandalore's offer to become a Mandalorian.
You're welcome. I'm happy to share!
