Barbara looked torn between snatching Lydia from the nasty, dirty, demon man, and trying to respect the girl's feelings. How could a murderous demon be any kinds of friends with this sweet, innocent girl? But, if she wanted to help Lydia, then she guessed she'd have to get used to...what was his name? Bug juice?

"Mr. er, Juice," Barbara started. "From what Delia, er-[i]Lydia[/i] has told us, you have been a very important...adult figure in her life." The word 'parental' didn't seem to fit. "I think Adam and I can respect that, but, if we are going to welcome you into our home, we need to set some ground rules." 

She paused, looking down at Lydia. "But maybe in the car?" Where strangers couldn't walk up and see this incredibly bizarre exchange going down. 

"No problems, Babs!" Beetlejuice promptly turned into a cat and jumped into Lydia's arms, purring loudly.
