I can't understand her lying about a such an easily verifiable thing like a doctor's appointment. That could be disproven by LE in a matter of minutes.
If she did, that could almost go in her favor toward the "loony" side, as it makes no sense at all.
Actually it does. Here is Terri Horman, concerned supermom finding symptoms of seizures in Kyron before Kaine and Desiree even know. Here is the same woman saving the day by making a doctor's appointment for him. It was supposed to go to how good of a mom she is. It was supposed to show that she knew more about him than his own bio parents did. It was supposed to help uphold how she couldn't have done this because look how much she cared for Kyron, she was saving his life by seeing things his own bio parents couldn't. Kaine and Desiree were supposed to be in shock and awe that they missed the symptoms, but thank GOD for a great stepmother like Terri to see it time and take steps to save his life. They'd support her innocence with the police because she was saving his life. And someone who does that can't possibly want to hurt the same child.
And remember, this is a woman with an ego who thought she could charm and manipulate anyone, even the police. She figured they would just believe her about the appointment and think she was a good mom and couldn't have done this. With Kaine and Desiree singing her praises to the police, they wouldn't have bothered to think she was suspicious or had done anything. She was counting on impressing Kaine and Desiree so they could impress upon the police how innocent she was so that she wouldn't be looked into in the first place, so no one would find out that she lied about the appointment. She apparently severely underestimated not only LE but Kaine and Desiree as well. She made a HUGE mistake by trying to bring something in to make her look good that could easily be disproven and make her look bad instead.
People who do bad things, when they get finally get caught, a lot of the time it's not for big mistakes. It's for small ones they didn't even see coming. Terri thought this was just another lie that people would believe. In the big picture of things, I highly doubt the appointment was the biggest piece of the puzzle for her. It was a small piece that she didn't even consider might be her downfall.
I mean honestly, without the appointment, Terri doesn't look nearly as suspicious. But that appointment, that contrived lie, in my opinion, was the first domino that made everything else fall. I bet when LE talked to that doctor, IMO, that doctor had no idea who she was much less about any appointment, and that turned LE onto Terri like lasers. I know we don't know what the doctor said, but would the appointment still be such a big deal if yes, she had one? It would be nothing to be talked about if it was verified. Instead, the bio parents had no idea, and I'm betting the doctor had no idea either.
That's another thing about people who do bad things. They don't always think everything through. Terri probably only thought about what would make her look good, what would be a good alibi for her. She didn't think about the fact that LE would verify that lie, or that people wouldn't believe her. After all, she's supermom, saving the day with a child not even her own blood. Why would anyone doubt that and think she had anything to do with what happened to Kyron?
It's Terri's severe underestimating of her own power and the intelligence of people in general that is going to be her biggest downfall. And the appointment is just one piece that shows that. Lunacy it is to think that people wouldn't see right through that. It just shows how much ego she has and how powerful she thought she was that she would snow everyone with her perfect loving mother routine, but how ironic how much it hasn't worked in her favor.
I bet she kicks herself everyday that she ever brought the appointment into this. If it's proven that she lied about that, then what else would she lie about? I don't blame LE, if they did prove that the appointment was a fake, for continuing to look into Terri and her story.
