Does his appearance link to your current session and when you logged in?
For example, if I log in while he's still at the Tower, go off and do some strikes until after the time he leaves, and travel back to the Tower, will he be gone?
Or would I have to log out and log in for him to leave? Hope I'm explaining things well enough.

He appears at exactly 1AM* PST on Friday, and leaves at exactly 1AM* PST on Sundays. It does not matter what you are doing client side, he will disappear at this time.
Watch him vanish.
He appears in the same fashion, but I could not find a good video that wasn't bloated with graphics/misinformation to link.
*It was 2 AM PDT when we were observing DST, so when the clocks move ahead an hour in the spring, the time will likely return to 2 AM PDT.
