Thanks for the feedback, henrytemp! I guess it won't be long until we see if Colin is telling the truth or not, but that scene at the ranger station will get even crazier, I'm having a bit of trouble to write it down exactly as I'm envisioning it in my head, that's why it's taking so long for me to post the follow-up. I'm building Emily as a rival to Jennifer, a complete opposite; their squabble will come to a peak in one of the chapters from the sequel. Robert and Daniel are good guesses for being the mystery man, and even Robert can be a suspect, remember he could have lied to Gavin.
My view on Zack and Ashley is that, had they been introduced as soon as Taylor and Hannah became friends, they would be the power couple of the story by now, with nothing capable of breaking them up. But, seeing as they were introduced much later, only two years before the story, and with a long previous relationship on Ash's side, can a new one with Zack last? It's up in the air,
I guess what I'm doing with the relationships at this stage of the story is the following: it's a theme in which everyone starts questioning if the person they've been dating/crushing on is the right person for them. Zack is slowly putting the mess that was the triangle with Vicky and Heather behind him to maybe pursue something with Ashley. On her end, Ashley has been questioning since the beginning if Brandon is the right guy for her, and now that they broke up, she may have found someone more compatible to her in Zack. Brandon has been rediscovering an old attraction to Victoria, and his lack of finesse may very well push her into something she isn't ready for, now that she decided to get over Zack and Dustin. Heather is still in construction, but she still wants Zack, apparently, even after she had a powerful experience with another woman, Leah. As for Chloe and Gavin, something that they do on "At The Cabin"'s end will be their plot on the sequel. Kurt will fulfill a fantasy he didn't even know he had, and then he won't appear too much on the sequel.
