You were looking for Carl all over Alexandria, you had already finished your guard to take care of the wall and you wanted to spend time with him, although after searching for a while you didn't see him anywhere, so you assumed that as he often did, he had left Alexandria without telling anyone.

You went to the back of the wall, a blind spot where there was never any surveillance, and you jumped over the wall, leaving the safe walls of Alexandria to search for him.

And after a while of searching you found him lying on some dry leaves at his feet, half leaning against the trunk of a tree. He appeared to be resting with his sheriff hat over his face.
