Hecathe is clearly angry...

"Aaaaaaa!" LeiLei suddenly screamed as she covered her ears and crouched down to the ground, "I don't know! I don't know! Stop it! Leave me alone!" 

Somehow, Hecathe had managed to touch a triggering topic that managed to break LeiLei down. 

LeiLei knew the murderer and there was no doubt about that, but for some reason, the girl refused to say anything and it almost seemed as if she didn't even believe her own memories. 

Hecathe sighed as he shook his head in disappointment, "If that's how you want to be, there's nothing I can do about it. You are better off forgetting the whole thing and don't you dare speak a word about avenging your folks again." 

Hecathe didn't bother waiting for a response from the girl nor did he ask any further questions as he left LeiLei alone and turned around, walking towards the door.
