[Okay wow, what the heck is this serious question. Lance seems... a little surprised by the gravity of it, though he does give it some serious consideration after a moment.]

There's no way I could give up on going back, [Mild clarification out of the way first.] I couldn;t do that to my team, my family... or my entire universe, really.

[His brow furrows.]

But if I seriously couldn't.... I guess I'd have to stay here. There are... thousands of other sites like this one, right? Knowing what these guys are up to.. and knowing what we know now, it'd be hard to just... up and leave without doing something to shut it all down.

[A sigh.]

...Plus, I think doing that would give me more closure on what happened with Shiro.
