Dumbledore was taken back by the display of affection, but he smiled and laughed softly none the less. "Do not apologise I am quite flattered," he said warmly. "In fact I think a hug is the least you deserve for what you have done today," Dumbledore spoke and with without delay reached forwards and pulled both the Doctor and Robin into a hug.<br/><br/>"Happiest...day...of...my life," the Doctor breathed, hugging the old man back quickly before letting go and sheepishly scratching the back of his head. "Sorry to tell you this Sir but...I resign."<br/><br/>"I accept your resignation," Dumbledore chuckled. "Your gifts would be wasted here Doctor. Although I am sure there is much that you could teach us."<br/><br/>"Oh I don't know, I think it would be pretty boring in comparison to the stuff you could teach me," the Doctor said before reaching forwards and shaking Dumbledore's hand. "I'll visit at least. There is no way that I can just leave this planet be, it's far too interesting."<br/><br/>"I look forward to the return of both you and your wife, Doctor" Dumbledore said pleasantly, causing the Doctor's eyes to widen in surprise before he blushed.<br/><br/>"Uh...no we're not really married we're just..." The Doctor began, but then noticed the way that Dumbledore's eyes were twinkling mischievously and grinned before waggling his finger at the old man. "Oh you... come on Robin, it's time to let this old rogue run his school," the Doctor said before jogging to the TARDIS.<br/><br/>"See you Harry, you take care!" The Doctor called back to him. "You and your friends take care and make sure to kick Draco about when he's being a brat," he called before hopping over the table that stood before the TARDIS and opening the doors. "Oh and that reminds me, Snape! Sorry about the face!" He called to the potions teacher, who had walked into the room with bandages circling his bruise nose. "See you later my wonderful world of magic!"<br/><br/>"Doctor..." Dumbledore called out to him, his voice soft, but yet his tone seemed to carry a weight that seemed cold and foreboding. "Some words of advice before you leave. Your future is wild and dangerous, you may need these words in the dearest of times."<br/><br/>"Okay...lay them on me," the Doctor said eagerly, hanging off the door of the TARDIS.<br/><br/>"Beware who you let into your heart Doctor," Dumbledore spoke softly, his stare hard as he looked into the Doctor's eyes. "You must be cautious about who you share your world with," Dumbledore said before his gaze dropped to Robin and then back to the Doctor. "Beware the Child of Time, Doctor."<br/><br/>The Doctor was quiet. The smile had vanished from his face. A dark look had replaced it as his brow narrowed. His golden eyes seemed to grow just as cold and stern as Dumbledore's. He motioned for Robin to follow him before stepping into the TARDIS without another word.
