I suppose it could be looked at as though, in all the drama that just happened and getting what he wanted by being accepted by M&J, it slipped his mind that he had to meet with Jade. However, it is one of those choices that are very prevalent in this game where you feel like he could have done both. He could have gone to meet Jade by saying he had somewhere to be and he'd see M&J back at the dorm later, or at the very least he could have spoken to Jade in Ep 5 or 6 to straighten things out with Jade, maybe tell a little white lie about why he didn't show up and try again with her.
