<p>Well, actually, it was precisely BECAUSE he was so interested in his new boss's position (rather than simply being promoted, he wanted the position of CTO; the next best thing would be to keep his enemies closer and perhaps become the right hand of his new boss) that he did it. He and his wife both waltzed into their house, knowing that they were going to try their very hardest to manipulate them and/or somehow get in their good graces. They worked together, actually, both spouses trying to find a weakness in their married hosts. Joanna flirted subtly with the husband, pretending to be interested in his wines. Meanwhile, Tyrell went for the shock factor, and attempted to catch his boss's wife off guard with a repulsively blunt and rather rude remark about her marriage, as they're are both watching their respective spouses lean in close and speak in somewhat hushed tones about 'smelling the wine' properly. It works, slightly. She gets agitated, reacts negatively, and leaves the room with the impression that Tyrell is not impressed with her husband, not afraid to speak his mind, and is aware that his boss is likely attracted to his wife (Joanna). He reaches out to her, although his reaching out was the equivalent of a verbal slap.
</p><p>She goes to pee. Clear her mind, calm down. An intimate moment, one that he shamelessly, emotionlessly, disrupts. When she doesn't force him out of the bathroom, doesn't scream, doesn't hide from him: she gives in to his attempted domination. Like animals, it's clear that his gaze pierces her, clear that there isn't very many reasons why a stranger would walk in on the opposite sex like so. Ah. Seduction. His game is seduction, and his wife is aware; she allows it, to reach their elusive goals. (Frankly, she might be more sociopathic than he.) His boss's wife loses her barriers and, quite literally, spreads her legs. She accepts his nonspoken command. She will give in. Tyrell decided at this point that he would not give her what she wanted, politely thanks her for the evening, and then leaves her hanging. Leaves her lacking. In his mind, now she will want him, and now he has found a weakness to exploit.
</p><p>PS. It's also probable that his off kilter actions are due to his abnormally high intelligence. Geniuses are usually oddballs; besides that, Tyrell seems to be slowly losing his grip on his cherished discipline.--- A Wikia contributor 24.4.52.250
