Lucas retconned that one. Originally they were just soldiers, when they talked they had different voices, they were varying heights, etc. On the DVD version, I think he redid their voices so they all sound like Jango Fett, plus Lucas says they are clones. He also redid Boba Fett's voice so it sounds like Jango Fett (the original Boba Voice was better). The bunker was inside the shield, that is why they take the shuttle in and have the Imps shut down the shield on their way in. He has already surrendered and Vader has his weapon. He also can try to take a shot at the Emperor.

Vader is stupid. When he realized that Luke was his son, he should have thought, "Really? Then, all those years ago, when the emperor told me that Leaha was dead, she was actually still alive and later gave birth to my son. He lied to me! What a dick. But noooooo.... Vader's not that bright. He's so wrapped up in the "join me in the dark side" that he doesn't even stop to think about it.
Bottom line was the Luke had to Kill Vader to COMPLETE is journey to the darkside so it would in fact still only be 2 siths. However, the Emperor left that fact out when discussing Luke with Vader.
Maybe he did think about it and that's why he wanted Luke to join him and kill the Emperor. All Siths lust for power. They are controlled by emotion/hate to begin with. The dark side will twists their mind. Luke felt the conflict within him but in the end Vader killed his master even though he knew it would cost him is own life.
Vader probably IS thinking Palpatine is a dick and lied to him. Once he finds out about Luke between Star Wars and Empire Strikes Back, from that point on he's obsessed with finding his son and turning him to the Dark Side to overthrow the Emperor. From that moment on in Vader's eyes, Palpatine is a dead man. Vader just plays it cool when he's around the Emperor so he never suspects anything. But Palpatine ain't dumb either, so he's simultaneously plotting Vader's demise and intends to replace him with Luke. Of course, I'm ignoring the retarted prequels in all of this which quite frankly make Anakin out to be really dumb and extremely impatient. In other words, the polar opposite of the Darth Vader we all know and love from the Holy Trilogy. As far as Chewie fighting alongside Yoda, the problem I have with that is that he makes fun of Ben Kenobi in the Death Star for all of his Jedi mumbo jumbo. Yet he witnessed firsthand how bad ass the Jedi are(some of them anyway) during the Clone Wars. Maybe not a massive plothole, but a headscratcher at the very least.
OB1 first finds Chewbacca in the Mos Eiesley space port when the were trying to leave Tatooine. Chewie knew Jedi and knew he could be trusted. Vader never looked for Luke because he thought his child was dead. Padme was in love with Anakin. He was pretty darn cool. The fall of the Republic was the will of the force.
some of these... I understand Chewbacca and Yoda would have never crossed paths again. Padme probably forgave Anakin for slaughtering the sandpeople, she was nice and forgiving like that. Siths like to screw each other over. It had happened at least twice before. Palpatine had decided Anakin wasn't worth ruling the galaxy with, and plotted to replace him. (kind of like with Count Dooku back when... except that Anakin was more of an actual threat to the Emperor) I am surprised Vader didn't figure out the Luke thing (at least not for 20 years), but he may not have known he still had children since Padme was buried to appear still pregnant. C3PO had to have his mind wiped for good reason; he was pretty talkative. But R2D2 didn't have his mind wiped. He still recognized Obi-Wan years later. What I do wonder: C3PO seemed to understand R2D2's language of beeps and noises. Did he not tell him anything the entire time? Maybe he just knew not to tell him...
how come owen lars didnt recognize c3po and r2d2 in star wars when he was buying them? afterall they did meet in episode 2. his brother created c3po
Both droids have their minds wiped. Maybe the chip Leia planted in him also had information as to what OB1 looked like?
Because they became pretty standard droid units. Remember the "other" C3PO in Bespin. Plus R2 units seem to be pretty generic.
All those protocol and astromech druids look alike. If I came across my brother's old car at a dealership, I would think that's the same model of car that my brother had and not think it may have been his.
