I am not sure. It sounds like if you have done everything you are supposed to do that you are then taken to the Swamp House automatically. Take a look at the walkthrough again:
Tex decides to talk to St. Germaine hoping that he could get some information about the notorious Tesla Egg from him. After blowing Ariel's cover, she then explains about the Tesla Legacy Society. After the FMV, another one follows where Tex comes over to The Resort after Ariel invites him to 'share information'. After she starts walking toward you, you will have three options. Now, the choice you make here will affect your future relationships, and some FMV's as well. Be it either with Taylor, Chelsee, or Ariel. Pick the option of your preference and have some popcorn. Left-most option is for Chelsee, the middle one is for Ariel, and the right-most one is for Taylor. After you take your pick, someone knocks on the door.Guess who it is? Why, if it isn't Taylor! Oh wow, Tex will have it rough. Ouch. Pick your option and according to the option you picked, a FMV will follow. After the FMV, Tex arrives on the outer yard of Margaret Leonard's Swamp House. Time to investigate this place. Maybe we'll find out something about her or that Mantus guy.
