It wasn't supposed to be like this. He felt so incredibly guilty, so incredibly responsible for all of it. Sirius looked like hell, but it didn't surprise him. After what he'd witnessed between Sirius and Lucius Malfoy, it really came as no shock that Sirius would appear worse for wear. The thought made his stomach wrench, but it was what it was.
Sirius didn't owe him anything. He certainly didn't deserve to be punched.
He looked over at James and Lily, half embracing each other, then back down at Sirius. The shattered pieces of his heart hurt so much as he recalled what he'd seen the night before, but it hurt even more to see Sirius looking so broken and lost. He had to set his own pain aside. Sirius was more important.
"You need to get to bed, Padfoot," he said, resolving his tone and pushing back his sadness. He reached out and offered him his hand, praying his emotions wouldn't betray his facade of calm.
