This will appeal to very few people outside of Battlestar Galactica fans, but I’m halfway through season 2 and have figured out a very simple way to detect a Cylon. As fans will know, the new versions of Cylons can now present themselves in human form, as you’ll see above. These Cylons think, act, and communicate like humans, and some of them don’t even realize that they’re Cylons (they’re sleepers, you see).

Throughout the series, the humans have been working on a Cylon detection tool. Dr. Gaius is the one that has been given this job, and although we don’t know exactly what his detection tool requires, I think I have it figured out. See, the one thing that all of these humanoid cylons have in common is that their spines light up like Christmas trees when they’re having sex. It’s basically the same idea as shining a flashlight through your cheek, but on your spine. After some contemplation, it became obvious that the only way to detect Cylons is to do ‘em doggy-style. As a follow-up, by process of simple deduction, it turns out that the Liberator is the best way to detect Cylons. Who knew?
