Yo! Mandalore sounds really natural. I think you’re set with that part.

I actually think “your padawan” fits less now, in comparison. Was that the best version of “padawan” you could find?
I’m guessing you may have already tried to have him say “Ahsoka”? I wonder if it would fit better, because of course we know who Ahsoka is, but it might feel weird for Obi-Wan to refer to Ahsoka as his padawan, because a hypothetical non-Clone Wars watcher might be like “wait, Anakin has a padawan?”
Plus, is she still technically his padawan? But people wouldn’t necessarily question it if he just said “Ahsoka”.

Don’t get me wrong, though, I think “your padawan” would still be more than great. Great work. Totally worth the effort so far, I think!
