easiest first, as for the thing that broke off, i really thought it was a shuttle... if you watch the second episode (i think, maybe first, they blended together pretty seemlessly...) it shows a shot of the shuttle from the outside, and in the few microseconds we saw the shuttle at the end of the 3rd episode, they looked pretty similar to me...
hey, thats at best, at worst... it really was a piece of crap that just fell off the ship, maybe an attempt to emphasise just how badly the ship is damaged...
@Orodum: yes, it may have been from a different part of the ship...but are you saying you think there can only be the one or two shuttles on the entire ship? you may have meant the damaged shuttle the senator died in (thank god, i hate that actor), but i cant think of why anyone would want to launch in that...
as for the two scientists who went through the gate, sure, maybe they didnt get back, but then who cares? would you really want to waste 30 seconds on seeing them freeze to death or get eaten by wild animals or whatever? they were idiots, and demonstrated that they cant take orders, so meh, its pretty easy to assume they are lost causes... i automatically assumed that was the last we'd see of them once they went through the gate.
as for Rush telling Greer (legend, btw, idn why, but i think he's great) to shoot the scientist with the remote, well, why not? the guy had the remote for getting back to the Destiny, and he's trying to run away on a fools errand, he deserves a bullet in the shoulder.
However, when Rush came through the gate and told everyone "Greer shot him" not, "i told Greer to shoot him" thats just selfish self preserverance.... though, that said... Rush is already on thin ice... people, the sheep they are, wouldnt think about the fact the scientist broke 'the rules' and tried to leave with the remote, stranding the rest of the team on that desert planet, they would only think about the fact that the 'bastard' Rush told a soldier to shoot an unarmed civilian, so i can understand why he said what he did, and in all honesty, he didnt lie...
i do agree that Rush is the most knowledgeable person on the ship... i see him as a bit of a McKay/Carter hybrid... which is really unimaginitive... but nonetheless, he has McKay's arrogance, and Carter's intelligence and 'hardness' to make tough decisions... unfortunately, these two traits make him a grade A asshole if you get in his way, and only a Grade B asshole otherwise... still, like Zelenka in atlantis said: "Soldiers, they treat you like crap until they need you to solve all their problems" yes, Rush is an asshole, but he's worth it.
As for the fight between Rush and Greer... i can understand both parties... Greer is trained to survive in hostile environments etc and, like all soldiers, is trained to hate loosing. so he thinks he has situational authority over Rush. but then Rush thinks he's got the authority because he's smarter/more knowledgeable, AND, hes worked his butt off to get where he is, while Greer was thrown there for whatever reason, and got there just by pulling a trigger effectively... so, ultimate truth, Greer should have called the shots because he is trained in survival tactics etc, and Rush should hve just called shots in relation to the mission as it pertained to aquiring the Lime for the air scrubbers...
lastly, with the speech about worth etc... Rush was right, and the Senator was right... the injured people was all but useless if not a burden, why waste one healthy body/mind so a bunch of resource drains can survive for a short while longer? yes, it was convenient that he was saving his own ass, but he's absolutely right, nonetheless, and people need to get over this fear of the ends justifying the means. the end almost ALWAYS justifies the means. if the ends are worth spending one short human life (as in injured/soon to die), then go for it. If it was my dad id be pissed/upset (excuse the understatement) too, but it does not detract from the ultimate truth of it.
so yeah, Rush is an ass who is manipulating people to his own ends, but if hes smart enough to do it and no one can stop him or see through it, well...
in any case, im sure he wants to get home as well, there is no point in doing all the research if you cant get home to utilise it. at least he has the presence of mind to fix the current problems while avoiding future ones, even if it involves lying...
and idn, everyone likes the fat gamer nerd... i think he's quite useless... its the goddamn Average Joe Hero syndrome people are going through now, they like to see average losers turned into heros... i spend enough time with losers in real life, i want my entertainment to take me away from 'real life' and transport me to a place where things are simple, where hero's are extraodinary people, and where people generally arent petty, contemptable sheep.
the fact they moved away from the Jack O'Neill/John Shepard hero at the front of the team also pisses me off...
oh well, all i can hope for is some nice fireworks...
