I want to say any of his big projects in TR. For instance, the fact that he was able to recreate his floating chair without the aid of fontech was a big accomplishment for him and he'd love to show off how resourceful and how much of a genius he is! I imagine Jade would judge him for taking advantage of Pokemon like that but hey it could've been way worse...speaking from experience with other projects.

...but I'm pretty sure the closer answer is he would have a grand time introducing Kato to Jade because Jade meet my partner—I got a partner—I am so proud of him and our relationship. That entire CR has been first after first for him, and a lot of things he thought he would never have so hell yeah he's going to be pretty pleased about it.
