Is everyone in act 3 her?

replaying the game again and wow, EVERYONE is orin. conversation with a guard, orin. yenna the kid, orin. lens the journalist, orin. not to mention the other doppelgangers like dribbles or the assassins under the open hand temple. i didnt do most of this when i first played the game but now that im having more conversations its like, EVERYONES orin.

i was literally thinking about making this post but before i did i spoke to some guard watching the refugees, sure enough, IT WAS HER.

did i speak only to the npcs that are orin? is the outer city orin? am i orin?
