Peter made the same connection the younger Evey had, at just about the same instant. He remembered the strange influx of people into die Festung some time back. There had been the man, Jesse, and another Murphy. And there had been food left for them when the people had finally vanished.
This was that City? He had been grateful at the time, surprised and pleased. Even if he'd still been confused by the situation. And now, this City had taken them in, even given Peter back the last place that had ever felt like a home. It had brought him here, with his friends - some even in pairs. Amazing.
Was that the consciousness he had felt so briefly? He thought it might have been. Peter listened a bit longer on how the conversation had shifted, but then he felt Evey draw away from him, heard her alarm. Brandt. Shit.
He shut his eyes and focused on the man. He could locate anyone he knew, anyone he was asked about, the same way Molly Walker had been able to, just by thinking about them. The geography of the City was unknown to him, but as he concentrated on the power, Peter saw images of gates, dark cells, prison doors. He let out his breath in relief. He's in a prison, he relayed to Evey, opening his eyes again. Since he had an open arm, he used it to embrace Leeloo more firmly and returned her kiss.
He understood Evey almost too well. Her sudden fear that she might have lost him had unnerved her enough that she had fled from the feeling, from the source of it. She was relieved of course, that had been clear, but the brush with despair had been too close, and she needed space now to step back, to center herself and get stable. As much as he wanted to reach out again, to hold and reassure her, all he would do is suffocate her.
He couldn't do it. He wouldn't allow himself to clip her wings, to make herself vulnerable. She needed this. Needed the distance. So, as much as he hated it, he let her go back into the TARDIS, where she could feel useful. Let me know if you need anything, he sent to her. I'm here when you need me.
To the woman he held, he asked, in her native tongue, "Do you want to stay here, or would you like to see my apartment?"
The younger Evey would be back shortly. He would be there to meet her.
