Leia: Han! {kiss}
Leia: Luke! {hug}
Han: {sotto voce} What are we doing about C-3-Nute-O?
Chewbacca: Remember her beeps? I can assure you there's nothing to worry about.
Luke: I thought as much.
Luke: Princess... Sorry for losing you in the forest.
Leia: It's okay. Seems I had a slightly more comfortable trip here than you did.
Chewbacca: Much cheaper, as well.
C-3PO: Good job following my plan, Luke.
Yoda's voice: Yes, most obedient.
Luke: Thanks... er... Sally.
Yoda's voice: Done well, it was. Only five steps on the Path remain.
Han: Obedient? He didn't follow my plan at all!
C-3PO: Make that very good job.
