I will stick to my theory until we know otherwise. I went to bed last night and slept well too, finally. I feel more at ease today as well. I hope they are good signs.
I know TS set up EJ with someone. I think EJ does not know where he is, but TS knows who he's with. Of course, she cannnot contact them or else LE will find Gabriel. Her only source of communication right now is the internet and the media. That's why her face is all over it, all the time, acting smug and confident. She has to communicate to the person who has him that "all is well, don't worry, everything's fine...see, they're looking at EJ, it's okay, don't panic, don't hand him over, keep calm, it will blow over like I said."
The person who has him, I also believe is watching the internet, and FB as well. Everything to this point has been a TS attempt to keep that person calm, but with the fan site so heated up, TS is concerned this person will crack under the pressure like EJ. So, she's now making it private, and removing things so this person will hopefully calm down. TS is just trying to show this person she is still in control.
This is all just MHO of course. It's the only thing that the most sense to me. Someone uninvolved but a POI, wouldn't put their face out there this much.
EJ's cracking, but she won't be able to help unless she really saw the person that has Gabriel (TS may have taken Gabriel to meet them though). TS knows, but she will never say, she is that self-righteous and believes she is doing the right thing...the right thing in Tammiland.
I think he is either in TX, or TS/EJ took him to Victoria, where someone drove to Houston and hopped a plane for anywhere.
I hope that Logan's trip is helpful, for him at least. Whoever has Gabriel, I hope they are moved by seeing this daddy trying so hard to find his little buddy.
