River: There has to be another way. Use the Tardis. Use something! Save her, yes, but for God’s sake, be sensible! [She goes to slap him and he catches her wrist] How are you even doing that? I’m not really here.
The Doctor: You’re always here to me. And I always listen. And I can always see you.
River: Then why didn’t you speak to me?
The Doctor: Because I thought it would hurt too much
.River: I believe I could have coped.
The Doctor: No. I thought it would hurt me. And I was right [He kisses her passionately] Since no one in this room can see you, God knows how that looked.[Vastra, Jenny and Strax look awkwardly at each other]
The Doctor: There is a time to live, and a time to sleep. You are an echo, River. Like Clara, like all of us in the end, my fault, I know. But you should have faded by now.
River: It’s hard to leave, when you haven’t said goodbye.
The Doctor: Then tell me, because I don’t know – how do I say it?
River: There’s only one way I’d accept – if you ever loved me, say it like you’re going to come back.
The Doctor: Well then. See you around, Professor River Song.
River: Til the next time, Doctor.
The Doctor: Don’t wait up
.River: Oh, and there’s one more thing.
The Doctor: Isn’t there always?
River: I was mentally linked with Clara. If she’s really dead, then how can I still be here?
The Doctor: Okay. How?
River: Spoilers! Goodbye, sweetie.
