This is a good idea. I might try this for people who live way far away. And it's good writing practice!

So either
-- a story about Auron trying to raise/not kill a little!Tidus
or
-- SC verse, Auron actually admitting to Roy that he considers him close like Jecht and Braska. I leave to your discretion how sober/not sober Auron would be in making this declaration.
