Yes. ( He's not going to like the reason why, as it makes far less sense. Javert has already long come to terms with the confusing nature of this place, so his delivery isn't laced with frustration, but rather, weariness. )

Resurrection is even a possibility, though it is not always a sure thing. It all depends on the state of your lantern. If it can be repaired, then you will return. If it cannot, then you will die — for good.

I advise you keep it close, and do not let it out of your sight.
