Loki's stare can make a lot of people stutter. If he didn't unnerve or fluster Peter at all, he'd be worried.

"Truly, you've never had fresh cherries?" The ones here are pitted, and maybe sugared a little, but otherwise seem to be right off the tree as far as Loki can tell. He likes them very much, himself. "That seems a pity. Are they so scarce on Midgard?"

He's aware by now that Asgard was a little bit spoiled, with anything fresh that couldn't be grown there rolling in easily enough from Alfheim or other worlds they traded with. That, and as a prince he had access to all the best of everything, but even the lower social tiers were not left to suffer malnutrition, not under Odin's reign and not when Loki took over in secret.

Had he never left Asgard, he probably wouldn't know what it was like to be truly hungry.
