Oliver made a beeline for headquarters, having heard Kara's call over the communicator. He'd responded immediately and was glad to hear Barbara would be there, too. The more people working on Diana's predicament, the better.
It took him no time at all to make it inside. His friend was in trouble and Oliver wasn't going to stand by and do nothing. Hearing Barbara, he couldn't help but smile and altered his course, headed for the kitchen. "Anything I can do to help?" Oliver eyed Barbara, knowing how well she worked with computers. He wasn't terrible himself, but Barbara outmatched him, no question about it.
