He'll take the last watch and it'll already be dark for 2 hours by then, but that shouldn't be a problem. He'll just cast Light on something high to make it basically work like a sort of street lantern. Besides, he may be older than most of you, he's not deaf and has a good pair of ears to pick up sounds with. :-)<br/><br/>He also has a passive perception of 15 so he should be able to pick things up with relative ease.
