You guys don't need Tidus to turn around and pretend he isn't here? Okay, well, he can not do that. This, however, isn't really awkward to Tidus; watching the two of them, the gestures and show of friendship that are familiar across different worlds, places, even with their nuances of culture and personalities.

He feels sorry that they're going to have to part, but glad as well that Jingyi got to see friends and family, for as annoying of a return as it must have been. Chucked out and off the train as he was, probably predicting from then that this wouldn't end well.

(Not being in your body is a pretty big clue.)

So he's smiling, small as it is, to be witness to a pair, and this he can feel more comfortable to, to be allowed a peek into their lives - Jingyi's life, his comforts of a good friend.

He won't even change his look, make any conscious note or observation to Jingyi's closed eyes, as he opens them.

"I can if you want me to! What do you think?" Cheery, far more than how he arrived, the few seconds after it, and he directs the question momentarily to Sizhui. He waves a fist close to his shoulder, as if direction to some path back. "You wanna fly back? Then you can hold me."

As if this is a far better alternative than carrying.
