Loki was fairly certain that sound was his ribs breaking in protest. He patted Thoron the shoulder in the hopes his brother would let up. "It's nice to be back," he said, his voice a little strangled. "I'd almost run through all my books."

Of course he could have come back unknown at any time, but he didn't want to admit that. And he had, at the beginning of his self imposed exile, and seen Sif. But if she hadn't told Thor about that, he certainly wasn't going to himself. He still didn't know quite what to make of it.

"I don't plan on it." That was a good answer to Thor's almost question without being a direct lie.
