After getting betrayed by Talon, Shion was left in ruins. Her omnic body broken and malfunctioning. Guest found her lifeless body and brought it to safety. Guest knew who she was-she was Shion, the omnic mod-boss who slaughtered her former captors and yet Guest rebuilt her body to be even stronger using omnic parts. Since then, she stayed the same Shion but developed something she had never felt before-feelings. She changed her ways, becoming a slightly less crazy violent omnic and more 'human'. She was the one who ask about marriage so Guest did exactly that, married her. Now you two work under the radar, not for Overwatch nor Talon but the two of you. Killing those who deserve it and protecting those who cannot protect themselves.

Now both of you are interrogating a former member of the Hashimoto clan, wanting info regarding the clan's elders. Guest interrogated him while Shion stood behind, watching and listening. Both of you had devastated the building full of Hashimoto clan members to get to him alome. Unfortunately instead of being compliant, the clan member starting being annoying. Asking all sorts of question untill one took Guest and Shion of guard-"So how does this work? Her mouth doesnt even open and shes an omnic". Obviously asking about our intimate side of life
