Nyx didn't know, so he just watched the other man try and explain what it was. There was imense confusion on his face, while Clint did a poor job on explaining what a hippo was. Slowly Nyx shook his head. He still didn't know what a hippo was.
When Nyx got the go-ahead, he crouched down and held his hand out. "Hello Lucky, I'm Nyx." And like that he shook the dog's paw and fed him the crush to his pizza. To say the least, Nyx respected animals greatly.
"Well, it was here when I needed it most." Nyx shrugged and looked about. "No. I'm just very new, and trying to gain some understanding on what's what and where's where." Returning his gaze to the other man, he held his hand out. "Nyx Ulric." Redundant sure, but Clint was his own person compared to Lucky the dog.
