Saito: Hey, I see you've changed.
Peter Browning: Sorry?
Saito: Ahh... I'm sorry. I mistook you for a friend.
Peter Browning: Well, good looking fellow, I'm sure.
Eames: That's Fischer's projection of Browning. Let's follow him and see how he behaves.
Eames: Because how he acts will tell us if Fischer is starting to suspect him just the way we want him to.
In the second level dream Saito sees Browning in the hotel lobby and thinks he is an Eames impersonation. Eames signals Saito just in the nick of time.
