The real Helina.

Sado informed the imposter she was going to take a crack at the prisoner again before they reached their next destination. She went back to the holding cell and removed Helina taking out the gag from her mouth. Helina immediately ordered Sado enable protocol 000 and Sado did her eyes blinking for a nanosecond. Sado looked at Helina and told her that she believed there was someone on the bridge who was not who they represented. Most probably an android. Helina thought no shit sherlock but said nothing she had come up with a plan and informed Sado.

"Sado I intend to set off an EMP generator so you will need to shut down your circuits to protect yourself."

Sado nodded in agreement and shut herself down until Helina reactivated her. Helina snuck out of the holding agree and head to the weapons cabinet. The imposter just happened to see her on the internal monitors and called Sado but got no response. The android checked the auto nav computer was engaged and then headed down to the lower deck. She confronted Helina who shot a laser beam at the android but it failed to do any damage. The android shot its own laser beam from her finger hitting Helina and stunning her then approached.

Helina was stunned but conscious as the android stood over her emotionless and lifted her up so they were eye to eye.

"Silly human you think a laser would work on me?"

"Silly android I knew it would not work but this will"

Helina hit the button on the micro-generator and it released its electromagnetic pulse which fried the androids circuits. Helina prised open the fingers and she fell to the floor landing on her feet. She immediately headed back to the holding area and reactivated Sado who after running her start-up routine joined Helina on the lower deck. They examined the fried android and Sado informed Helina that the android was a product of AndroTech and was built in a plant back on Mars. Androtech supplied most utility androids for ships and colonies but someone had reprogrammed this one without all of Asimov's robotic laws.

Sado said she would research as to where and who had the knowledge to do the reprogramming but first she had to return Helina to herself. She went to the computer and started to push buttons at an inhuman speed and Helina could feel the changes and soon he was back to her normal self. She asked Sado why the nanites had not been destroyed when the EMP was triggered and Sado surmised that Helina's biological systems protected them. She would need to get them removed at a proper medical facility but for the moment Sado had made them dormant.

They both headed to the bridge to see where the android was taking them.
