Yeah, can't see these two having drinks or otherwise.
re: lightsaber. So wait, Obi's going to actually request people not say anything about it? Unless it was out in the open at the point the entire Iron Man, Batty & co (with u.s. government support as backup) showed up? Then his personal knowledge of it would be absolutely nihil anyway. And there's enough weird stuff happening that a lightsaber (if he even did know about it but I'll say he does not to let you play out what you want with it) would be just another tuesday at the office.
It's probably (as a suggestion) better to say Obi DIDN'T draw attention to the saber by going 'Hey guys, can you ignore the whole lightsaber thing?' because Pete would probably not care too much and a bunch of foul language and a chewing out would ensue. That's just a trainwreck due to the situation being what it was, that I don't even have the energy to deal with at this juncture. So it's safe not to go there so that it stays secret, like you want it to stay.
I mean, that's what I'm understanding here. Maybe, possibly. I'm not sure why he'd vocally request something he wants to keep quiet. :|
Otherwise, the man's dealt with fairies and part of his team was a shapeshifting alien that ran around as John Lennon before, etc, so yeah. Can't get any weirder than that. And that was his job, to deal with it all. So at whatever point you choose, a jedi running around with a lightsaber is going to be like...everyday is halloween in the grand scheme of things, where Pete's concerned.
If it's important to you then can just leave it be and I'll just try to keep mister sharp-eyed observation blinded with one hand held over his eyes. It's safest if Obi probably just says nothing and that way it doesn't have to be lost, unless you want it to be. Your call. I'm safe with handwave saying he doesn't know Obi has it, at all.
