He frowned as he focused his attention on the door, wondering how long it would
take before Fudge showed up with dementors at the ready, hungrily staring at him, eager
to swallow his soul.
He heard a familiar voice shout, "He's there!"
Sirius looked at the window, eyes wide as the strangest sight appeared before him:
Harry Potter riding on the back of a hippogriff with a tiny, bushy-haired witch clinging to
him, her eyes shut tight.
The flying creature tapped on the window with the tip of its wings.
Sirius, forgetting his pain, rushed to the window and tried to open it. "Locked!"
"Stand back!" the girl yelled as she pulled out her wand, still gripping the back of
Harry's robes with her left hand. "Alohomora!"
The window sprang open.
Sirius stared at them, gobsmacked. Hadn't Dumbledore just said, not less than a
few minutes ago, that Harry was in the hospital wing? How had they come to save him so
quickly? How had they not been noticed? Where the fuck did they get a hippogriff on such
short notice?
"Get on!" Harry shouted, holding a hand out to him. "There's not much time.
You've got to get out of here. The dementors are coming. We saw Macnair going to fetch
them."
With no further prompting, Sirius pulled himself through the window and took
Harry's hand as he climbed onto the back of the hippogriff. He threw a leg over the large
flying beast and leant forward to look at the small girl with an apology in his eyes.
Mia, he thought as he looked at her, placing a hand on her waist to steady himself.
And that's when he felt it. The bond. It was her. The thrumming was faint, barely there and,
had he not previously felt it at its strongest, he might have missed the sensation altogether
as, apparently, she had.
She was young. So young, it was quite uncomfortable to look at her, let alone touch
her, despite the need to do so in order to stay balanced on the hippogriff's back. She was a
virtual stranger to him, but somehow... she was still Mia.
"Okay, Buckbeak, up!" Harry shouted, and the creature took flight once again. "Up
to the tower, come on!"
