After everything's said and done, Red was still stuck in a dilemma. One way or the other, he had to sacrifice either Scar's recovery or the entire escape itself, and he knew all too well that he couldn't choose the latter.
Still, it's not like we could just leave Scar behind. He went so far as to help us escape back then and there's no way we'd reciprocate that by abandoning him. Red said to himself.
But when it comes to choosing sides, there was no way he'd choose the welfare of one member rather than Block-16 as a whole.
In the end, he just returned everyone's gazes and sighed. "I have an idea on what to do but does anyone have any suggestions? And Freckles, how far could Scar walk without his wounds reopening?"
