The other day as I watched ESB for the umpteenth-millionth time it struck me how weird the Skywalker family would be if everyone had been aware of their relationships throughout the OT. How would certain situations have differed (i.e. Leia's torture in ANH) or conversations (Han & Luke posturing over Leia in ANH). For all of ANH, Vader does not know he has any children, just going about his business scaring the bajeezus out of the galaxy. But throughout ESB he knows Luke is his son. This does change how he views this young man. How? Well, mostly he just wants to convert him to the darkside so they can overthrow the Emperor & rule the galaxy together. But Vader still doesn't know about Leia which means he also doesn't know that his little girl has a boyfriend. This has led to some very interesting conversations in the -Wan house. "What if Vader did know about Leia?"

Suddenly, Darth Vader is not a Sith chasing the wrong ship through space in an attempt to capture Luke, but a father chasing down his daughter & her boyfriend.


Here we go!!

LEIA: This bucket of bolts is never going to get us past that blockade.

Vader isn't just trying to prevent the Millenium Falcon from escaping Hoth, he's trying to catch Han, tell him to stay away from his daughter. Han & Leia flee their hideout in the nick of time. For now, they're putting some distance between themselves & her very angry dad.

VADER: Asteroids do not concern me, Admiral. I want that ship and not excuses.

In his crazed fatherly mind, Vader will stop at nothing to catch this scoundrel who has clearly warped his daughter's sense of right & wrong. He'll chase Han to the ends of the universe - there's no way he's getting out of "the talk" with dear old dad.

VADER: ...there will be a substantial reward for the one who finds
the Millennium Falcon. You are free to use any methods necessary, but
I want them alive. No disintegrations.

It's time for dad to send out reinforcements. He's got friends that his daughter doesn't know about. He'll get this boyfriend of hers somehow, someway. Even if that means...tricking one of Han's own friends into betraying him.

VADER: We would be honored if you would join us.
LANDO: I had no choice. They arrived right before you did. I'm sorry.

Finally, Vader has that good-for-nothing boyfriend all to himself. He'd rather not do this in front of his daughter, but at this point there doesn't seem to be a choice. He'll torture him in private while he sends Leia to her room. And by "her room" I mean prison cell.

LANDO: Lord Vader, what about Leia and the Wookiee?
VADER: They must never again leave this city.

Finally, Vader has set his daughter up with the guy he had always hoped she end up with - someone who's not afraid to work for him. Someone who knows how to make her father happy. Lando. Sure, she can keep her pet Wookiee. That's the least he can do for Leia since he's going to turn the love of her life into a candy bar.

VADER: The Empire will compensate you if he dies. Put him in!

Party time! Now with Han out of the way, Leia hopefully hooking up with Lando, Vader can turn his attention to his rebel son. It's time to pass on the family business, but first that boy needs a haircut.

VADER: Calrissian, take the princess and the Wookiee to my ship.
LANDO: You said they'd be left in the city under my supervision.
VADER: I am altering the deal. Pray I don't alter it any further.

Clearly, Leia is not interested in Lando and her father knows that she's not above jumping into a space ship & flying off to uncharted territories to hide for long periods of time. Vader, not wanting to take any chances, decides that Lando isn't strong enough to make Leia stay in Cloud City, so Vader is taking her back with him.

He has big plans to introduce her to Admiral Piett.
