-Does anything else happened?
-Tv screen was covered in redish-black substance.
-Can you bring it here?
-Yes, give me a minute.
After 3 minutes, jar with black liquid was analysed. The SIM and liquid was made out of the same material.
-First device that was infected probably was your tv, David. Object B (The real form of Forgotten) taken the SIM to use it in situation where he can't destroy the device or get out of it.
-That means we need device without calculation power, and without spot for a SIM.
-We can use USB.
