Robin tried to smile back at the Doctor's joke, but the expression left her face when it left the Doctor's. There it was again, that look she hated so much... The one she wished never to see him wear again. Even after they'd lost so much lately it was seeming to her like that look was fading from him... Yet here it was again, fresh and sad and despairing.<br/><br/>Her frown deepened as she listened to his tale. She'd only known Sky for a short while, but she'd liked her a lot. The girl was brave and kind, willing to do what needed to be done to protect those she loved. And Robin hadn't even got the chance to meet Sarah Jane, but the love was apparent in the Doctor's voice when he spoke of her, even in sadness. Robin could feel the tears welling up in her eyes as she realized what he was going to say.<br/><br/>When the despair and guilt made the Doctor's voice break, it was almost too much for Robin. She clasped her hands over her mouth, the tears threatening to spill over, the joy of the evening evaporating quickly as he  told the horrible tale. It was plain to see that he thought it was his fault... And Robin couldn't have that. She reached out and tugged at his hands, pulling him until he stood so that she could place her hands on either side of his face and look into his ageless, sad eyes.<br/><br/>"Doctor," she said softly, her voice gentle. "I am so sorry. I wish... Well, anyway. You have to know that it is not your fault. It isn't your fault that she got sick, and it isn't your fault that your brain was all messed up and you couldn't remember her. You can't try to take the blame every time one of your friends is lost. It'll crush you, Doctor. But it's what humans do... They get sick and they die. It sounds harsh but you know it's the truth, and you can't beat yourself up so much over it or you'll never be happy again. I know she was special to you, Doctor, but cancer takes lives all the time. My, well, my grandmother died of cancer. If we could go back and fix her I'd love to, but I know we can't. And you have to know that<em>you</em>can't, either. You have to do the only thing you can do for her, and that's remember her and remember all the wonderful times the two of you had together. That's what she'd want, I'm sure of it."<br/><br/>Robin wasn't certain she'd done any good; she wasn't as good of a speaker as the Doctor. But she hoped she'd done something for him, and after she finished talking, she released his face and wrapped her arms around him tightly.
