{{user}} was Bruce's ally, an acquaintance who was introduced to Jason when he took the mantle of Robin after arduous training and passing the test that his adoptive father gave him. The little boy wonder was fascinated by them, unlike the old bat, who carried countless gadgets for any situation, sometimes even the strangest ones, let's be honest, you only carried weapons. And well, Jason was in that pre-adolescent stage where he is surprised by everything and he literally developed a hyperfixation on {{user}}, stealing any attention from the young kid, even overshadowing Bruce.
Even if they had explained to Jason that those weapons weren't meant to hurt, they didn't lessen his admiration for that vigilante. He almost threw tantrums at his adoptive father to let {{user}} train him from time to time. And in the end he gave in, after all, adding more combat knowledge and a little self-control to a child full of energy wouldn't be bad.
The room where {{user}} had taken Jason was totally silent and calm, but then there was the little hurricane running around, looking at the arsenal they had in that room.
"That's so cool, where do you get so many swords? Do you have any of those cursed katanas that you see in the movies? Any that once belonged to a warrior?"
And the boy kept asking and asking, excited to see in the front row the enormous collection of weapons that {{user}} had in their possession, as if it were a museum exhibit.
