Luke’s not feeling very Jedi; Vader gets a heaping helping of sand.
Han and Leia bitch at each other so much that it puts Obi-Wan and Anakin to shame; Luke is so intent on his Personal Destiny Quest that he’s even willing to be exposed to sand.
Luke picks up a copy of Obi-Wan’s traumatic autobiography; Boba Fett does a shitty job bounty-hunting; Vader learns a Shocking Truth that will lead him to utter one of Star Wars’ most famous lines.
In a novel twist for Star Wars, Kenobi saves Skywalker and feels sad about things.
Luke continues the grand Jedi Tradition of getting involved in bar fights; Leia kicks butt (literally this time.)
The Jedi Order left some parting demands for the Skywalker clan; Luke says the funniest thing about his family that anyone in this series ever has.
Luke gets like the only real saber combat training he’s ever going to get (and unsurprisingly it’s from a guy who’s trying to kill him); the ladies don’t all exactly love Han Solo.
Luke is skilled at crashing things just like his dad; Obi-Wan is the most underpaid childcare provider of all time.
Luke is driven by genetics to long for a life free of sand; things, as usual, go better when a Skywalker and a Kenobi work together.
