Where do 你 think the characters are now.

I doubt they'd 移动 back to New York (unless you're talking about a 老友记 renewal which would need that link) but they'd all keep in contact. Monica and Chandler would still just have the kids - adopting when 你 already have kids is difficult unless there's a shortage of potential adoptive parents. I think Ross and Rachel would have one 或者 two 更多 children 由 now. They also would have gotten married. Phoebe and Mike 2 或者 3 kids.

I think Ross and Rachel would have another child after their wedding. They'll stay in New York for Ben.
Phoebe and Mike 2 kids. A girl and a boy.
I immagine Joey married with Alex and with a new duck.
