During the clash of Titans arc(season 2), Reiner, Historia, Bertholdt, Connie and Ymir find a young boy, all alone sitting in a corner.

Connie was the first one to approach the young boy. He bent down to be the same height as the boy and talked to him in a comforting tone.

"Little man, are you alright?"

Ymir and the others looked over to the scene with Connie and the young boy, and continued to watch as the scene continued on.
