The Shadow - S1.E12

After Marcello hacks into Alex's system Catalyst is put on high alert. Unable to give himself up, J.D Moon (hacker legend) is bought in to find the culprit.

Of course it doesn't take long before J.D. gets closer to the truth and Marcello gets nervous. The rest of the gang have to decide whether to help Marcello or not. But when Alex finds out the truth, Marcello gets his marching orders.
