Barbara's eyes narrow with anger and disbelief at the sight of a message on her screen. 'Nice try.' You sent. Some unknown hacker that somehow got in her system, in Batman's. How?

"Impossible." She mumbles to herself, her fingers working rapidly over the keyboard as she speaks to Bruce through the mic. "We have a problem."

Barbara tries to block you from their intercommunication, but all of the sudden, they realize someone else joined the call. You did it. You actually got in.
