Okay okay we talk a lot about Roland/Isono being a father figure for Seto and/or Mokuba but
What about the other way around?
Because honestly I can’t imagine someone being that devoted unless they really really want to protect those kids at any cost. A 16-year-old and an 11-year-old who have too much danger surrounding them and too many people wanting to harm them because they got so much power.
He puts up with
Extra McGee Seto’s weird behavior like throwing expensive ass gadgets at him instead of handing them over like a normal person without complaint, with regularly being put through about 30 near heart attacks at once, but also stays around for them even when Seto is no longer his boss, he takes his role as right hand man in the company seriously and keeps all the secrets, but also supports their passions (like ridiculously big Duel Monsters tournaments) in any way they ask. And of course he nearly collapses when Mokuba is in actual danger.
I’m sure he is some sort of father figure to them, but they most definitely are like his own children or nephews or god-children to him. He most likely is one of the very few people who knows their full history too and just wants to protect them.
