Real culprit.

Jason knew finding people involved would be half-win through the battle. As long as they find out who were the ones working for the drug, they will be able to find out the accomplice who dared to harm Arwen in such a way. 

"Aiden, I know you want to find it on your own, but I would still request you to let me handle this," Jason slowly said, his words might have sounded like a simple request, but there was a reason behind it. "You might have all the powers to find out on your own, but this field of industry is where my family excels. If you try to find out your own, it might uselessly garner you the attention which would be very favourable."

Aiden didn't say anything his silence favoured Jason's words. His expression remained grim, but after a brief while he nodded. "I want to know it all and it should be sooner than you could make."

Jason heaved a sigh of relief. Nodding back, he said, "Don't worry, I know what I have to do to get the details sooner."
