This is one of those times for me, that if Terri is guilty, she is both too cunning and too stupid for words, and I don't mean that as a flippant slam. I mean that literally. She planned this rather elaborate abduction and probably a murder as well, carried it out rather successfully thus far, but didn't envision that Desiree would come to Portland upon hearing her son was missing? It's just a little off, IMHO.
Also, what constitutes surprised? What is DY's interpretation of TH being surprised? Did Terri ask something along the lines of, "You're coming right now?" Is that the smoking gun with regard to this aspect of the case? The more and more this case relies on the nitpicks, the more and more concerned I become about the direction.
I don't want to delve into the rumor mill, but it's entirely possible that Desiree wasn't quite as involved in Kyron's life as we're being led to believe, and that Terri was simply surprised, in that moment, that she'd drop everything and come straight to Portland. I have little linkable evidence to back up the aforementioned opinion, but I will say that Kyron received a fishing pole for Christmas and TY said he'd been planning to finally take Kyron on fishing trip so he could use his new fishing pole. If you're actively involved in your stepson's life, six months is a long time to wait to take a little boy fishing to use his Christmas present. If Terri was in TY's position, she'd be crucified for how inattentive she was of him and how she didn't care enough to take him fishing so he could use his Christmas present.
I'll just go ahead and duck the tomatoes.
