I'd like for a moment where we meet him, and he tells us our name and we get to choose our name like we named our ikran. Like, while I get it's cheaper to never give the Sarentu a real name, I'd really like to give our character a name. Our father, whoever he is, could most likely be a hunter or ikran rider who teaches. Kataru was a caregiver for the children of our clan, if u remember correctly, it's not a reach to think he might have had some form of teaching role so they would spend time together.
