I am definitely up for Sabriel seeing Yzak during the first war, with him being an Angry Bastard and maybe seeing that his commander was a complete asshole.

And maybe him getting to see some of her memories in return, like her last conversation with her dad, or the final fight with Kerrigor at Wyverley College. Or her first encounter with Touchstone if he wants to see Sabriel awkwardly breathing on a wooden statue of a naked dude.
