"So is this it or is everyone that gets invited to my birthday parties waiting for me on the other side of the door?" The Doctor asked and began bending around the group to see into the chamber that lay beyond the door. "Have you got Mickey Smith in there? That would be just great if you had Mickey in there. I haven't made fun of a Smith in ages!"<br/><br/>"We only have the one Smith I'm afraid and her name is not Mickey Smith," Vastra replied with a shake of her head. The Doctor's face seemed to light up even more at the words.<br/><br/>"Sarah? You've got Sarah Jane Smith with you? Brilliant! I haven't seen Sarah in ages!" He exclaimed before suddenly letting out a yelp as Strax pushed him violently to one side.<br/><br/>"Look out sir! The robots have infiltrated our base and are launching their attack!" Strax yelled whilst pulling out a baton from the butler suit which he was wearing over his bulky small body. The baton sparked as he thrust at the air before him. The women seemed to sigh in frustration at the display and shake their heads in disapproval.<br/><br/>"Strax, for the tenth time. That is not one of the enemy robots. That is K-9," Madame Vastra sighed as she gestured to the robotic blue dog that drove across the stone floor towards them, wagging its radar ears happily.<br/><br/>"I don't trust it," Strax sneered as the metal dog as came closer. "Its heavily armed and very short. Tactically speaking we shouldn't trust anything short and heavily armed. We never know what trouble they could cause!"<br/><br/>"Don't be a hypocrite Strax," the voice of the young girl from the van grumbled as she walked out of the shadows and made her way through the open doorway. "If I see you talk to my dog that way again I'll bake like the potato you resemble," she growled before waving to K-9. "Come on boy! Follow me! There's a good dog!"<br/><br/>The Doctor stared after the girl with a look of befuddlement on his face. Slowly realisation dawned on him and he gawked at the girl before pointing after her and yelling; "Sky Smith! That's Sky Smith! Sarah Jane's adopted daughter!"<br/><br/>"She is and she's a godsend," Gwen Cooper spoke as she arrived on the scene and marched past the Doctor. "Without her we wouldn't have been able to find you, let alone keep this place running," she explained before gesturing for the group to follow her inside. "Come on, enough talking. We have a job to do."<br/><br/>"That's Sky Smith!" The Doctor repeated before turning to Robin, grinning with delight. "Robin! That girl is Sky Smith! You have no idea who she is! But that is Sky Smith! Daughter of Sarah Jane Smith! And you have no idea who that is either!"
