Oh Lex could physically feel his bad luck at work. What the hell kind of situation was he in? This was the trolley problem, but with broken hearts instead of death. One would argue that the lack of death made the situation easier. To those people, Lex would say hell hath no fury like a woman scorned.
On one hand, he just made an agreement with the group of ladies so he would feel scummy if he just abandoned them. On the other hand, they just had a business deal, but the ladies on the other side genuinely felt a connection between them and their partners, and wasn't that the whole reason they were risking their lives on this stupid planet?
When he heard the situation, Lex genuinely felt like breaking free of the restraints keeping him in place and just teleporting away. He wasn't here to play games anyway, he was here to find Sim. But the moment Cupid mentioned it, Lex felt like if he did that, then the outcome might be even worse.
