As the troll started to run pass, Deravan frowned. One of his kind would do this? Was he stupid or what. He started to run at him also, seeing the egg and fallowing, using his own speed to try to get to the guy, hoping to be able to stop him, before thinking rapidly and then getting one of his daggers out. He then threw it full force towards the troll at his leg, actually hitting hard at a weak spot, making the troll fall onto the floor, dropping the egg, which fortunately didn't break from this. Deravan then rushed forwards, hoping to be able to pin the guy down.
"Stealing from a dragon, what are you, crazy!" he then yelled at the thief, before he took his katana out and rushed forwards. Lucky he hit the guy at least in the leg using his dagger like that. He would need to go and grab his dagger again afterwards.
