Ice cream was a new treat that Aragorn had discovered during the hot summer he'd been here. They had nothing like it back in Middle Earth, not even in Gondor, where things were more advanced than they were most places. He'd been introduced to it and had been excited to find how refreshing it was, and how it could cool you down. And sweet treats were still quite special to him, although the cost of sugar was not nearly so high here.
He was in line, looking through the different flavors. He hadn't been through nearly all of them yet - probably not even through five of them - but he was curious and wanted to try something new.
When the man spoke to him, he looked over at him and smiled a bit.
"I'm afraid I'm not the one to ask. I never knew ice cream existed before this summer."
