[Having a plan is nice. As difficult as Connor has been being a lot, it's mostly because he's in kind of a 'teenager' faze; it's still extremely new to him to be able to say no, and to be able to do--or not do--whatever he wants, and so he's been taking advantage of that. But there's still an inherent part of him that wants to help and accomplish things, and it isn't just because of his programming.

So he's content to help with this, nodding in agreement with the first statement. But as for the questions--]

If I'm not damaged, I can last for a very long time without any additional
maintenance; power may eventually become an issue, but not any time soon.

[However, that's only if he remains undamaged.]

If I take minor damage, I can self repair everything but lost thirium, which is our equivalent of blood. If a biocomponent is seriously damaged it will require a replacement, and if it's an essential component I will likely shut down.

[He's still getting used to considering himself 'alive', and so that he would die; 'shut down' is the familiar, easy term.]

Similarly, losing too much thirium will have the same effect as blood loss would for a human.

[And the potential of all of this--and thinking about it and how tenuous the situation is--is pretty distressing now that he can feel fear. But he's trying to ignore it, because there's nothing he can do about it at the moment other than not get damaged.]
