Lucci flows through the katas with his eyes closed. He doesn't need to think about the familiar stances; they're almost instinctual after being his outlet for so long. His grandfather hadn't allowed him to continue his classes, of course, but he couldn't erase the knowledge he already had. Lucci had kept it up in stolen moments when Garp couldn't enforce his ban; one of the few prohibited pleasures he allowed himself. But going down memory lane isn't the point of the katas.
He needs to think.
He can hide it for a couple of weeks longer. Maybe three. Not longer. Thankfully it's already too late to do something about it. The knowledge fills him with warmth and happiness. He won't lose this one. He can keep it.
He doesn't even realise he's come to a halt, standing still with his hands on his stomach and a proud, happy smile on his face.
He can keep it.
