But there are more immediate concerns than politics as Rush endeavors to learn as much about the ship and how it operates as fast as he can, and teams of civilians and military explore the ship for whatever might be of use. Although nobody trusts Rush, and our hacker-slacker Eli Wallace (David Blue) is beginning to gain the trust of everyone, it is Rush who has the knowledge to put it all together and find a solution to their common dilemma. But can they trust him? It's almost beside the point, since their survival depends him. As Scott says, for now they need him.
The immediate concern is identifying a way to close shuttle door, necessary to isolate the leak. But who would volunteer for this suicide mission? And how can anyone order another human being to death for the greater good? But someone must go, and someone must give the order.
Here's where the difference in style, personality, and leadership begin to come into high relief between nominal hero Col. Young, nominal villain Nicholas Rush. Dr. Rush is a pragmatist; objective, perhaps Machiavellian, he is not only willing to sacrifice a life for the greater good of the crew but begins to compile a list of those he would consider as candidates: those perhaps less valuable to their survival. Sacrifice of someone whose skills might allow them to survive either in the short or long term makes no sense to him. On the other hand, Col. Young is only willing to sacrifice himself, noting that he is injured, and furthermore he could not ask anyone to make such a sacrifice. Rush points out that "politicians order soldiers to sacrifice themselves every day for the greater good." How is this different? Who is right? By sacrificing himself (or Rush offering to sacrifice himself), Young would deprive the survivors of their leader. Is that the right thing to do, either?
The point is made moot when Chloe's (Elyse Lévesque) father, Sen. Alan Armstrong, dying of internal injuries, disappears from his cabin. He knows he's dying, and makes a decision for himself, knowing, I would suspect, that no one would have suggested it to the powerful man. Even Rush says he would not have chosen him. Despite the understanding that Armstrong is not long for this world whether or not they survive this crisis.
