"Oh, uh. An old friend of mine -- Kanan's oldest friend -- needed some help. Morfizo of Moraga. He, uh. Apparently he'd joined the Rebellion while I wasn't looking, and the Empire had picked him up. Not that his wife knows I'm a Rebel, just -- it was one hell of a coincidence."

Or, you know. The Force.

"So we took my old ship that Morfizo was keeping safe for me, and uh. Went to Lahn to break him out of prison. You, uh. Remember our old friend Rae Sloane? Turns out she's a Vice Admiral now. That was an unpleasant surprise."
