— Hey, who are you, man?
— I don't remember who I am.
— None of us do.
— Okay, we have no phone and no computer. There's no way to contact the authorities. All we have to go on is this.
— So we know our names. I'm Sharon!
— I... Michael.
— You've met Lukas.
I don't think I comprehend this well. I understand all we have just fine; it means something like that's all we've got here. But I don't know how to make proper sense of to go on.
Just dawned on me. Does that mean something like all we have (all we've got) to continue figuring out who we are is this (and then we throws a bunch of identification cards on the table, apparently the identification cards belong to them).
