Residual mech consciousness, but it's actively trying to kill you.
That little scrap of consciousness desperately clings to life. It believes with such a strong conviction that it is still alive, that they are still in the cockpit. That they are still in control. You aren't a pilot, you're an invader in that pilot's body. You're forcing a machine that isn't yours to contort to your motions, instead of its muscle memory built with years of trauma and experience. You are a virus to be purged.
