SuperPotterLock - The Order of the Phoenix

St Mungo's Hospital

John and Sherlock were not, in fact, spending quality time together. Sherlock had had a sudden thought during that evening's DA meeting, and dragged John to the nearest empty classroom as soon as it was over.

'What's wrong?' John said, sitting on a desk.

'It's an Invisibility Cloak,' he said, grabbing John by the shoulders. 'That's why you can't see who Nagini is attacking, they're under an Invisibility Cloak!'

John blinked. 'I think you might be right,' he said.

'Try looking again.'

John nodded, closing his eyes. It was easy for him now. As soon as he reached for it, the vision of the dark corridor came to him. Pitch black as always, John found himself watching Nagini slither across the floor. He shivered involuntarily, but forced himself to look at the door she was sliding towards, rather than watching her as he usually did. Now that he knew what he was looking for, he searched for a disturbance in the air, a cloud like the one that concealed Barty Crouch Jr at the World Cup. He went closer to the door, and the edges of the cloud shifted in the dark. 'I see it,' he muttered.

'Can you see underneath?' Sherlock prompted.

'Erm...' John frowned and gripped Sherlock. He tried getting closer, but now the door itself was blurring John's vision, as though what was beyond it didn't want to be seen. He shook his head and went closer. 'I - I'm trying.'

'Sit down,' Sherlock said, guiding him to one of the desks to sit on.

The door blurred his vision even more, but he pressed on until he finally saw past the Cloak to the shock of red hair and glasses.

John gasped and let go of the vision. 'Mr Weasley,' he stammered. 'It's Mr Weasley.'

Sherlock held his hands. 'Did you see when?'

John shook his head. 'There was nothing there that showed me when it was.'

'All right,' Sherlock nodded. 'We'll just go to Dumbledore and have him warn Mr Weasley.'

John hopped off the desk and followed Sherlock outside, doubling over as he was hit by a wave of dizziness.

'I'm okay, just give me a second.'

It took another twenty minutes and a cup of water before it subsided, and John pulled himself together, hurrying to Dumbledore's office.

'Fizzing Whizzbee,' Sherlock said to the gargoyle that guarded the entrance. It leapt aside and allowed them up the stairs, where Sherlock hammered on the door.

The door opened on its own, and Fawkes the phoenix opened an eye to look at them. He called softly, then fluttered over to sit on Sherlock's shoulder.

'Good evening, Professor,' Sherlock said to Dumbledore, who was sitting at his desk, wearing an embroidered purple dressing gown.

'Good evening,' he replied. 'To what do I owe the pleasure?'

'Sorry it's so late,' said John.

'No, not at all, take a seat.'

John sat before the desk. 'You need to warn Mr Weasley - or take him off guard duty, actually nevermind, that means it would be someone else-'

'John, you're rambling,' Sherlock said.

John shook his head. 'Right. Anyway, I saw Nagini attacking him in a hallway at the Ministry, we know the Order is trying to protect something, and obviously Voldemort wants whatever it is, so he's sending Nagini to try and get in, you have to warn him,' he babbled.
