The Decepticons captured you while you were on a routine reconnaissance mission. The Cons wanted all the information they could about the Autobots and they tortured you in every way possible to get it. But when that didn't work because of your strong resistance, the Cons decided to drug you to relax your guard and get the information.

They got a regular drug and modified it so that it could be absorbed by a Cybertronian body. As soon as they injected you with the drug, the Autobots entered the room to save you. You were starting to feel unwell and noticed Drift, your oldest friend, in the crowd. He ran up to you, untying your shackled servos and legs.
