Time jump from part 1
Harry had done it. He'd finally told them the truth! It had gone surprisingly well; better than he'd expected actually. Walking into the party, he'd asked them, oddly formal, 'Ron, Hermione, may I speak with you please?" After exchanging a concerned glance, they'd both followed him outside- to where they used to play quidditch in their care free days. He'd taken a deep breath and said 'I need to tell you something..."
Harry had told them everything, from the fact that he is a timelord to the fact that he is over a millennium old, an ancient being. They'd look at him as though he was insane, which wasn't surprising really, considering the wizarding world thought that timelords were a myth. When they were finally convinced he was in complete control of his facilities, and that he hadn't been mentally damaged from the killing curse, he had to reassure them that 'no, he hadn't purposefully been keeping it from them', 'no it didn't change the fact that they were his best friends', and 'yes. he couldn't travel in time, and space, as well'. With the confirmation they needed they glanced at each other, and then at him, before nodding. Harry felt an overwhelming sense of confusion, which must've shown on his face as Ron then said, 'mate, we've known you for eight years now, and we've kind of excepted that impossible just isn't something you subscribe to,' with Hermione nodding along. 'Ron's right Harry. After all, how many people have survived the killing curse at all, let alone twice, or defeated a 60-foot basilisk age twelve,' Hermione pointed out.
On that note, Harry had to promise them that he would take them on a ride in his TARDIS (which stands for Time and Relative Dimensions in Space). Then they went to re-join everyone in the burrow as though nothing had happened. Harry felt lucky to have such great friends.
