IIRC, Thailand was not the first place he landed. I think he wanted to go to Japan (because he's a weeb), but couldn't get in due to COVID restrictions, so he spent some time in South Korea, and then I think Thailand came afterwards.
The simplest explanation for Andrew is he has "yellow fever." Pretty sure he's even admitted so.
Again, I am not a fan of Andrew, but Barnes is an utter shithead for insinuating what he did.
One good thing about Andrew is I doubt he's gonna turn out like Nick if he goes back to asia. Unless he's a fucking idiot. Asian drug laws are pretty draconian, from what I understand. I think in some countries, like Singapore and Indonesia, they straight up execute your ass if it's over a certain amount.
