Why did Lice disappear

As it turned out Lice was spooked by Luno. When the thug came to see him, he thought Dusty was on to the deal he made with Paine. Afraid of what they'd do to him, he just took off. When he ran out of money, he realized how much he missed Shelly and came back. When Lice came back and saw Billy on the floor, he went into a jealous rage and Shelly had to conk him on the head to stop him. He apologized for his behavior. He grabbed onto the aquarium when he tried to get up and pulled the entire thing on top of him.
