"AH but there are," she responds immediately, smiling. "It's possible that on different worlds, technology is written a little differently, much like ... different countries have different languages. But the structure of language is always the same. We all need to communicate some sense of people, places or things. And we need to place them into current, future or past tense."

Though, there's a lot to talk about there. Including the theories Felicity's been reading about on how changing an entire language makes a whole society think differently. But that's for another time.

"Well, technology works just like that. It's created by humans, but the general theoretical structure is the same. We all have these little devices-" Felicity gestures to her phone. "-and they need to connect to each other somehow. Not only that, they need to get regular updates from somewhere else. So if you want to figure out the front door, back door, and any other kind of opening, you just follow the trail. How does this little device communicate out? How does it receive data in? Then, the rest is just like figuring out the specific syntax."

A beat before: "Soooo long story short, there are tons of traitorous back fences on the Internet, and how good your digital home security is ... well, it's all based on the person who built the house and how good he or she was at it."
