Derek opens his mouth to echo back "there are" in question form, but Felicity keeps going and he figures if he keeps his mouth shut, she'll explain. She doesn't disappoint. Granted, most of what she's just said largely goes over Derek's head, but it's the thought that counts.

"How can you 'follow the trail,' so to speak? How do you get in to see that sort of information? I mean, I can barely text, so maybe this is like trying to teach a blind man to see, but I'm not really sure I understand..." Derek admits.

And he's not sure he really cares, except that he likes when she's talking because she sounds incredibly confident and it sounds good on her. He smiles a little at the summarization. "So basically, they should be putting you in charge of making sure we're all digitally safe," he says, following her lead and dropping "cyber" because it's apparently not the right word and he doesn't want to continue to sound like an idiot.
