While Ted is speaking to Beard, Sherlock leaves the room for a moment, returning with a phone that he hands to Joan.

"Emergencies only."

"Got it," she says, sliding it into her pocket. "Which safehouse are we using?"

"The one by the docks. Do you remember the evasive measures I taught you?"

"Yes. I take it we don't have time to go back to Ted's apartment?"

"It would be best if you didn't. And best if you left your phones here."

Joan sighs and takes out her phone and puts it on the table.
