Beetlejuice suddenly popped into existence next to Lydia, and the Maitlands both jumped at least a good foot into the air. He smiled a toothy grin and flew over to them, wrapping an arm around each of their necks.

"Babs! Adam! It's good to finally meet you guys in the flesh," He gave them both a sloppy smooch on the cheek. "Rotting flesh, that is." He cackled and floated back over to Lydia. 

The Maitlands were in shock for a solid five minutes before either of them could speak up.

"Y-you're a demon?" Adam spluttered. 

"That's what they tell," Beetlejuice shrugged. 

"A-and you [i]kill[/i] people?!" 

"Sometimes," He shrugged again. "I only did what I had to do to keep my kid safe. If you two breathers can't accept that we're a package deal, then we're out. Right Lyds?"
