Robin accepted the miscellaneous items with a small smile on her face. But she really lit up when he handed her a key to the TARDIS. The Doctor treated this like it was no big deal, but Robin knew it was. It meant he trusted her... Trusted her with<em>his</em>ship, the most advanced piece of technology the universe held. His TARDIS, who had been the one constant companion through all his travels.<br/><br/>"I'm sure, Doctor," she said with a laugh, looking up at him. "As much as I'd love to see a version of your face that is actually capable of shutting up, I think this is the right place for me to be right now. I'm helping out my brother, I get a little more college experience... And you know you can drop in on me any time, I'll always be happy to see you." Her voice was a bit more sincere than normal, her face not quite as mischievous as it normally was.<br/><br/>"And if I get in trouble, I have the mobile. I won't go anywhere without it. Besides, it shouldn't be anything too bad!" She grinned, her purple eyes full of life, and flung herself at the Doctor. Wrapping her arms around his neck she pressed a kiss solidly on his cheek. "I'll miss you," she whispered in his ear.
