Reiner's eyes roam the establishment while Cater gets to work on his drink, noting all the nooks and crannies, the places that dust will collect. It's clean for now, but the upkeep must be considerable. He makes a mental note to contact Erwin and see if he'd like more help.

When he returns his gaze to Cater, it's a bit surprised, the question having caught him off-guard. How does he even begin to explain?

"We're from the same world," Reiner settles on saying. "Erwin was my commanding officer for a while, until we ended up on opposing sides. We get along pretty well now."

Which is skipping large sections of history, but it seems the most succinct way to explain things.

"I wasn't close to Levi, but he's very dear to people who are dear to me. He brought me here when I arrived in this world."
