John: Hi. Erm, no. It’s- it’s about Irene Adler.
Sherlock: Oh? Something happened? Has she come back?
John: No, she’s, erm… I just bumped into Mycroft downstairs. He had to take a call.
Sherlock: Is she back in London?
John: No. She’s, erm.. She’s in America.
John: Mmhmm. Got herself on a witness protection scheme, apparently. Dunno how she swung it, but, erm, well, you know.
Sherlock: I know what?
John: Well, you won’t be able to see her again.
Sherlock: Why would I want to see her again?
