Sam & Ruby/Claire - distracting Alastair.
She noticed how guarded he was, of course he was, he didn't like her doing what she was doing but frankly it had to be done, in return she didn't like leaving him on his own, going toward the sitting room alone.
But she supposed she couldn't think of a logical reason why not, and it seemed she might have been 'crowding him', 'pushing him'. Here she could show she wasn't.
Not that she wasn't gonna keep an ear out and be there the second he needed her. She turned into the kitchen not entirely happy with the decision but doing it anyway. He'd better be okay. He had to be. They just had to find him. That was it, just find him.
