Death threats to Claire wouldn't get him very far, but the danger to Toby was more important. She'd never told Toby what she could do – it still wasn't easy, admitting that ability – so she understood why he was trying to protect her, but it would only get him hurt. Gone was the voice that said Jareth was less of a danger than she was seeing him as right now, and left was the certainty that he would hurt Toby.
"Toby, get in the hotel now!" She all but screamed it at him and then swung her head back to face the Goblin King as she continued. "Just try it, and you'll find out how horrible even trying to hurt me can be for you."
But Jareth wasn't paying attention to her, he was looking at Toby. She watched recognition dawn on the Goblin King's face with a sick feeling in the pit of her gut, realizing the name she'd said and what conclusion he was drawing. Then she watched as another look settled on his face, looking to her like something feral and dangerous, something that was a true threat to Toby, to everyone. That feeling since leaving in the cab had increased exponentially, a call for violence as the only solution, violence as the only way to end this.
Later, she'd swear he'd started forward toward Toby, for she acted without thinking about it, just responded to the danger he had become. Pulling the gun free, she raised it and fired at Jareth's head. She had no way of knowing if he had a heart, if he was even truly flesh and blood, but shooting most anything in the head usually produced results.
"I said run," she yelled over her shoulder. If this didn't work, Toby needed to be out of danger.
