[Honestly... Jaune's not wrong, and despite himself, Sousei's expression softens. This ridiculous kid who was always clamoring for his praise--in the end, he went and grew up and didn't need it at all, really.

And there's something very worthwhile in seeing that.

Sousei straightens further, and nods.]

It is. I do not intend to return here after I have left. There is much to be done in my own world. [Like more treason!!! Sousei's good at that.]

And I believe your choice is clear.

[Something else that's impressive--Jaune's grown a lot, hasn't he?

At this point, Sousei thinks praise from him would be rather superfluous and undermining. Jaune didn't need his praise before to grow into the person he is now, and he certainly doesn't need it now that he's accomplished it all on his own. So instead... he salutes, a simple and calm gesture from one equal to another.]

And therefore, this is goodbye, Jaune.
