As Isobel began to speak, Archer had to resist the urge to clap a hand over her mouth. He cared about the girl, that much he knew. He wanted nothing more than for her to be healthy again, and her happiness was his concern. But at the moment, at this very second, he wanted nothing more than to shove her into a closet and lock the door.
He kept his breathing even and soft as he watched her, feeling the urge to kick her grow with every word. In the rational part of his mind, he knew that she was only trying to help. He knew that she wasn't malicious, and that she wasn't intending on landing him with a rabid inspector clinging to his back. But intent didn't always make up for action, and at the moment, her actions were getting him in a great deal of trouble.
When Luther finally spoke, Archer glanced to the other man blankly. This was not the last he would see of Inspector Luther, he knew that. As the other man moved past them to lead the way to the car, he rested a hand on Isobel's shoulder and spoke softly to her. "It's alright," he said. "I'm glad that you understand that you need help. And you'll get it. I promise you that."
Reaching the SUV, Archer ushered Isobel inside before climbing in after her. He didn't care if it was rude to leave Luther alone in the front - he wasn't leaving Isobel's side. When they reached the hospital, he glanced to her. "I'll go speak with someone. Stay here." With that, he climbed out of the car and walked into the hospital.
