Luke would go digging for his own phone, but it's probably dead thanks to the lake. He accepts Topher's instead and dials the number, dutifully putting in the extra digits for an international call.

He puts it to his ear and waits. After what must be several rings, he draws a breath, and flinches as someone says something rather cross to him about the time. "I'm sorry," he says automatically, immediately plowing on with "Is Sarah Jane there? Sarah Jane Smith?"

More grouchy tones from the other end of the line, and Luke's frown deepens. "Yeah, I must've," he says faintly, and then the call's over. He hands the phone back to Topher, not looking at the man. His eyes are wet.
