It's lucky(??) for Senku that Tidus isn't suspicious. He just knows that there's danger, even for Orange team - and a good barrier would be useful to anyone who needs it at the time. So, he only snorts as the joke comes up.

"I can tell you, we weren't running all over Spira with curtains falling out of our pockets!" Wow, that's weird to say out loud. Anyway. "I guess, it's about what people are gonna use, you know? And who's gonna help and buy. I'll use my points for supplies, sure, but I don't wanna buy something people don't wanna use."

He shrugs, a kind of helpless thing.

"But you help Orange handle their supplies now, right? So, if you get an idea of what'd be good for Orange from any of these..."
