Nathan drake but not Samuel drake
Probably yea he's an old man whose had a past we don't really know about would it be crazy to see an uncharted game with Victor goddamn Sullivan's story or any of the other people like tenzin or Salem
Probably yes a few phone calls or something
Probably not but they will keep the lost legacy crew together and Nathan might get a phone call or to from his old pals
Yes that's why he showed Nadine the ring and said "sorry but I'm spoken for"
