Who wants to leave their home? Homesickness; Tidus knows that well, and Jiang Cheng just reminds him all the more of the feeling, giving it up. The people and places you want to see, but can't.

Both he and Madoka know it well. Too well.

"Sure; take as much time as you need." They can give Jiang Cheng that much, and Tidus lowers his hand. A glance taken at Madoka (a very much dry Madoka), and he puts a hand on her shoulder in a small, friendly gesture.

"I think you can just think at us if you need us? Uh, this whole anchoring thing's a little weird... but if you want us to leave you to talk to people - we can look around together."

You know. Privacy! Jiang Cheng's an adult, and he doesn't need them following him all the time.
