I don't think he plans on company, because really how much creepier can you get than: "Do you wanna check out my van?" or "Come back to my van with me"

Even though I know his whole backstory, I still wouldn't come right away and I'm a 25 year old dude...

You may think that'll keep you safe, but creepy people can live in houses.

You might surprised how spacious half a queen bed can be, and he looks to be fit and trim overall. I don't think he's likely to have much trouble.

Half a queen is 25% smaller than a twin. It's 30" wide. Your shoulders are probably around 15" wide, wider if you are muscular/fit. Workable, sure, but with a companion it's hard to imagine describing that as spacious.

I shared a 20" wide camping mattress in a pinch. We are both very slender. Spooning was mandatory.

Oh. Well. Yeah, I can see how that's a real problem.

(Actually, I spent almost a decade married, so, gentle sarcasm aside, I can see how that might be a problem. On the other hand, I get the impression the cases aren't really parallel. I mean, if it were me and I had someone moving in, it'd be a good occasion for a rebuild to meet current needs, I think.)

If you need a fan to keep cool in that small space then a second body will make things a lot more uncomfortable.
