The smile was... a surprise, to say the least. Given everything he'd put the Autobot through, asked of him, it wouldn't have been a shock if Rung was less than thrilled to see him. At least, that was Kagerou's opinion of the situation. He supposed this time, it was a good thing he wasn't here to do that.

Not originally, anyway.

He bowed his head slightly, at the greeting, before following Rung inside. "Hello..."

As per his usual habit, he kept close to one wall, as if trying to flatten himself against it, and be less obtrusive. Even his wings folded tight to his back. "I'm fine," he said, quietly. "I found something. Recently. I thought... you could have it."
