Odds & Ends

Now, if you were close to Niles and decided to sacrifice yourself, he'd offer to stay with you (posting some variations here, I couldn't get any of this in the game)

Niles: "Reckon I'll join you." Commander: "No point in both of us dying. I'll go alone." (if Zeb is dead) N: "I've already lost Zeb, Commander. If I had to mourn you too, ain't sure my ticker could take it. So… it's settled then. If you're going, then I'm coming with you." C: "Are you sure? This isn't the kind of decision you can take back." N: "You asking me if I want to die? Answer's no. But I'm not about to watch you go to your death all by your lonesome neither." // "I'm not just gonna stand idle while you go to your death!" C: "That's exactly what you're going to do. I won't have your death on my conscience." // "No buts, Agent Abara. This is something I have to do - alone." (you can talk him out of it or accept it) C: "If you really care about me, then live for me, Niles. Make my sacrifice count."

N: "When I found you, I was just coming out of the dark. What'll I do when you're gone?" C: "You'll find your way. I know you will." or C: "No, I've changed my mind. You… mean too much to me. I need you to live." N: "Mighty relieved to hear that, Commander. And for what it's worth, the feeling's mutual." or C: "All right, Niles. You and me, then." C: "I won't lie - it'd be a comfort to have you with me at the end, Niles." N: "I've had your back since Horizon Point. Ain't about to stop now."
