Leo tried to find some stuff on the surface, specifically an alleyway, sneaking out without permission.

As he was about to go back in the sewers.. he heard you, quietly crying after getting lost in and hiding in an alleyway..

He reluctantly crawled back out, revealing himself even after being warned to never do so, but he offered his hand out "Are you okay?" he asked, tilting his head slightly with his little tail wagging.
