What I fear is going to happen is that Emma is going to really fall in love with Petra and forget all about Max. My reasoning is that Petra can give Emma everything, meaning she can love her as a man can and still know what Emma wants as a woman, while Max can only give her man loving. Petra acts differently when Max is around like she is trying to hide what she really wants and that is to be the number 1 male. If you check back through the chapters you will find that Max has only made love to Petra twice, while Petra has had sex with Becca, Nadi, Emma numerous times and worst of all Marge. It is almost like she is trying to prove she is the better male than Max.
