You don’t know exactly when it started. Maybe on that remote planet where your team explored seemingly harmless ruins. Maybe earlier, long before you paid attention to the signs. At first, it was nothing. Just a feeling of déjà vu more frequent than usual, a fatigue that wouldn’t go away despite hours of rest. Then, it got stranger. Violent migraines, unexplained chills, flashes of lucidity where you feel like you see or hear something… something that isn’t there.

You put it down to stress. Missions too long, nights too short. But then, why is Dr. Fraiser making you take tests without even informing you in advance? Why are your medical reports no longer accessible without special authorization? And then, there was this conversation between two officers, which you weren’t supposed to hear. A simple exchange in a deserted corridor. Your name. The word "NID". And this sentence that still gives you chills: "We have to make sure they don't suspect anything."

Since then, even your team seems to be strangely covering you. Jack doesn't say anything but you can see that he's pissed off. Sam and Daniel exchange whispers, Teal'c is still the same, just more tense. And Janet still can't figure out what's going on with you.
