Tabitha so naive or in denial?

Geesh I just don't get it. How does Tabitha choose to remain so clueless, so many episodes in, after finding out about the memories. I mean, she even acknowledges what Jade and Boyd are up to and trying to do in finding a way home. But what is she doing on her side except saying "No, no, no... Stop!". One would swear she never wants to leave the town, again, given what it is that she thinks she knows...

She has a young boy in Ethan who's curious and seems to (or want to) understand the world better than her. She has a daughter who is essentially time traveling. She has Jade and Boyd who have their own share of revelations and plans. In addition, her own experience in the From world, her own revelations and own memories, and those shared with Jade...

Last but not least you literally have a walking encyclopedia of the FROM world or at least the last 40 years or so, in Victor, at your disposal. And Victor who listens to you and for the most part is comfortable around you, and most likely you are the only person he would divulge information to. Apart from Ethan and Henry of course.

And talking about Henry. How did he get here? That's the other guy you had in your corner, in trying to figure out a way home.

Just annoying how all these important characters, and not only Tabitha, have many revelations, experiences, some of which have things in common but they always chose denial. Atleast share ALL your secrets with each other debate them, yes, and figure out a way to go home. Geesh.
