Biography
Samantha Robertson is the eldest daughter of John Robertson and Alison Robertson. After the Combine's takeover she was transferred to City 14, where she ended up sharing an apartment with Nathan Johnson. Although Samantha was a lot more serious and was irritated by Nathan's foolishness, the pair of them became friends. When Nathan was smitten with her, he proposed in which she accepted.

After their wedding she was ran over and killed by her ex-boyfriend Derrick Thompson. Years later Nathan would avenge Samantha's death by killing him, which brought closure over the incident.

Samantha would continue to be referenced to in the series. Her sister Hannah Robertson appeared regularly and Nathan would look out for her. However just over five years after Samantha's death, Hannah was murdered by Frank Blackstone.

Legacy and revival
Nathan would name him and Chell's daughter Samantha in honour of his late life. Samantha Johnson would later die after being killed by a cult.

On the tenth anniversary of Samantha's death Nathan visited her graveside shortly after going on the run from a mysterious group. He admitted that even if she had lived on, things wouldn't have been truly happy as he was a terrible person who brings misery and destruction to those around him. After leaving her grave, a mysterious figure visits the graveside. The man voices disappointment at Nathan's actions, and reveals that he will never learn about a (currently unknown) truth pertaining to Samantha.

Three years later, Nathan forced The G-Man to use his time bending abilities to send Nathan back to the day Samantha perished in the car crash, and managed to divert the car and save her life. Nathan discovered a lot of sinister secrets as a result of the changed timeline, such as Hannah Robertson not being Samantha's sister, but was actually a reincarnated Samantha; a result of her father John making a deal with an unknown group called "The Pact". Nathan and Samantha reconciled, and she discovered that she had originally been dead for over a decade before her revival. Samantha and Nathan found themselves in conflict with their robotic boss "The Mainframe", who wanted to kill the pair. Nathan forced Samantha to flee the facility as he destroyed the Mainframe, causing him to be buried in rubble.

Thirteen years later, Nathan reawakens to find the city under control of a new alien empire. He saves Samantha from the clutches of Derrick Thompson (the leader of the aliens) and they kill him before he can upload his mind into a newly improved Mainframe system. Samantha subsequently leaves City 14 to pursue a new life of freedom, whilst Nathan stays behind for her sake.
