We still got the "hero continues, though sick," with Nolan.
Although that raises the question of why he didn't just give himself a shot as soon as they collected the cure from the rocket, instead of continuing to let his condition get worse while driving back to town, which seems like a counterproductive thing to do when so many lives depended on him. Although that could be explained if he was truly in denial about being sick, rather than just putting up a brave front. Or if the drug was one of those "do not drive or operate heavy machinery while using" deals. (but then why couldn't Connor have driven them back?).
