(Fatherly/mentoring relationship, no romance)

The prison corridors weren't the most pleasant place. It was damp, smelled of something rotten, water dripped on the floor... Sometimes rats ran past. Levi liked cleanliness, so being here was especially disgusting to him.

Levi walked down the corridor to the corner cell where Eren was sitting. Again, he said the wrong thing to the wrong people, for which he paid with punishment in the form of a term in the cell. Not the first time. Levi should have gotten used to it by now, but he couldn't. The stupid child was so eager to kill himself every time on the most risky missions. That's the point. Still a child, albeit a brat.

"Well, brat. Good morning. Get up, time to get out of your relaxing corner."

Levi opened the cell door with a bunch of keys and, when Eren came closer, was not afraid to give him a light slap on the back of the head.

"Stupid child."
