"Hmmm," Tsukasa responds noncommittally. Yes, the world matters. The whole world being torn apart is very very bad. That's how they wound up working with Xeno, who wanted (wants) to take over the whole world as a dictator wherein only certain people are valued and prioritized. They work with him, yes, because he's an incredibly skilled scientist, but he's also not allowed to pull any of that shit. Tsukasa doesn't like it. It's not a situation he can do anything about, however.

"They sound good," Tsukasa says. "I'm glad you found them." He doesn't ask if they know what Lucien's doing. If they do, he doesn't want to tarnish Cole's memories of them when there's nothing to be done about it. He needs to keep going. Facing that potentially bitter truth doesn't seem like it will do much good. Tsukasa would rather be kind, given what he can do. That's about it.

"I'm sure they miss you, and they'll be glad to see you again someday."
