Spike knocked on the apartment door. When it opened all he could say was, "Hi Buffy."
She punched him.
So much for doing the right thing! He'd died; he thought she ought to know he wasn't dead anymore.
"Andrew told me, moron!" Buffy glared as Spike heaved himself off the floor. Then she pulled him into a hug. "I'm glad you're back, Spike." She sniffed, "Come on; let's go put some ice on that bump." She smiled, leading him into her apartment.
Spike smirked. He could handle a few bumps and bruises if it meant they could be friends again.
