The extra space is appreciated, the tension in Reiner's shoulders unwinding minutely. Realistically, that space won't make much difference if Levi decides to attack. But every little bit helps.

What. Was that a joke? Is Reiner supposed to laugh? Does Levi really think Reiner would shit on the floor? Is it some jab at how frightened Reiner is? Does he look like he's going to shit himself, just like Levi said on the beach? Why does Levi keep talking about shit?

"I'm not—," Reiner starts, then he just stares at Levi for a moment more, comically confused. Brows furrowed, he speaks slowly, utterly unsure how to handle this. "I'm not gonna shit on your floor."
