Sirius/Bellatrix
The Ministry was hell, no one had expected an attack like this, they'd been so unprepared he saw familiar faces all around him, people he'd known since he started here, people he'd known even longer and they were all fighting, doing what they could to get out.
He'd thought they had months for this, months to prepare to do anything, but no one had expected it to come so soon. He did what he could pushing people toward the direction of exits. There was shouting and the sound of spells flying around in the air past him as he left the Hitwizards offices, he needed to get out.
He'd promised James, no heroics. No matter how much of him wanted to stay and fight to try anything to stop this, it was too much chaos for just him. He needed to get out.
