Ever since Gao Yang mentioned to Glolov his intent to go to Idaho, Glolov immediately discussed with Yelena and her daughter the possibility of spending Christmas in Idaho. After all, for the Glolov family, Christmas was not until January 7th, so it would not be too late to go now. Yelena was content as long as she could be with Gao Yang, especially because the destination was his farm, so she was very excited and looked forward to the trip with Gao Yang.
Having decided to go to Idaho, Gao Yang informed Morgan that he would be leaving New York first, but he told Morgan that there was no need for his help this time. He had to see what Little Donnie was capable of. If Little Donnie couldn't safely get them to Idaho, Morgan would have to help bail them out. Of course, if Little Donnie managed the task without a hitch, then all would be well, and they wouldn't need to bother Morgan with such minor issues in the future.
