There's a flare of rejection in Hera's chest, and even though she knows Ahsoka's words are true, still she says --

"Kanan wanted to inspire people. He wanted to give them hope."

If there's going to have be a legacy, if they're never going to see him again, let there at least be that acknowledgment.

Because Hera can see clear as day where this is going, now that she's letting herself think about it.
