Pierre was banging Ilsa?
Well, having watched the 1st season several times I see clear signs that Pierre in fact was secretly banging Ilsa all the time, since the beginning. We all know of his womanizing expertise, and he's good at keeping appearences (as it's obvious he has many names). In ep.3 he jockingly says to Ilsa to take off her panties to tease Jackson, showing intimacy with her; in ep.6, she rubs her finger in his hand when he passes her a record. Meanwhile, she plays Jackson all the time, even getting furious with him in ep.4 for being "sentimental" with her. Looks to me that Pierre and Ilsa had a pure-sex relationship throughout season 1, while Ilsa knew of Jackson's romantic feelings for her - specially after ep.3 when Jackson tells it to Pierre.
What do you think?
