Between Flight and Longing (джен)

Attempting to find a cure for a critically ill Luke, Han travels to a backwater planet in the armpit of the galaxy, piloting an aging freighter discarded by the Alliance because it was unsafe to fly. With time running out for Luke, Han figures things couldn't get much worse.
He's been known to be wrong before.
