That's your sister, dude. I'm just teasing. I don't actually come up with that bullshit until Return of the Jedi. You can have sexual fantasies for now. Speaking of fantasies, I think I'll dress her in a gold bikini in the next movie.
Imperial fighters come in.
There is a battle between the rebels and the empire. MARK wears goggles that look as though they'd make it very hard to see clearly. The Imperial Walkers fall. Once they do, the rebels shoot them with the exact same blasters they used before that were ineffective. The Walkers explode this time, though.
