Beetlejuice had slowly grown progressively more mopey by the day. Even spending time with Lydia or Ash couldn't pull him out of his sulking. He couldn't use his powers, he couldn't talk or make jokes, he was constantly clean, he wasn't him anymore. And even worse, as each day passed, he became more and more anxious over Lydia and the others facing his mom. They couldn't possibly win. It was impossible. But no matter how many times he tried to tell Lydia to call it off, she wouldn't listen.
All he could think about recently was their time spent on the human battlefields. How he'd begged, cursed, pleaded that Lydia, still small and fragile, didn't get sent out into a literal warzone. A lot of good it did. And now, she was going off to war with one of the most powerful demons that the Netherworld had to offer, on his behalf, without him.
His stomach dropped when he heard Lydia utter the words he'd been dreading. Beetlejuice shook his head violently. He got down on his knees in front of Lydia, signing rabidly.
"You can't, Lyds! I can't lose you!"
