Me, too! I don't see a +4 but assuming you are doing a +5 and if he's up, head to bed.
I think he will likely head up. I am fading here so I'll leave you with this post on How to Handle Low Numbers. If he does come back down, just post and ask for help...someone will likely be around.
If you have any questions in the morning about whether to shoot, just post and ask for help. It's usually good to treat at +11 to see where he is.
