I get the feeling Nathan's not with Medicorps anymore. He wasn't in any of the footage from Venezuela. Lawson made himself known, of course. Nothing says disaster relief like making sure the cameras get Lawson's good angles! Curious if Nathan left willingly or if he was asked to leave.
I understand Katie's having issues and since she can't take her anger and grief out on her cheating husband she's passive aggressively taking it out on her family. I think it's shitty for her to let the rumors about Nathan swirl without doing anything to mitigate it. She's not only doing damage to Nathan's life, but also Esther and their children. I'm not a fan of Nathan, but I believe in innocent until proven guilty.
I still don't know why any of these people think Nathan has something to do with Katie's family issues. So I would get suspicious if she would deny it was Nathan. She hasn't denied anything about anybody so people should just stop speculating. If she wants to share more, let her, if she doesn't, also let her. It's her life, her drama, her family.
I don't think she is taking it out on her family. And if she did, well, can't blame her. She has more then one thing to complain about. And she is the victim so support her and help her heal.
Nathan and Esther going silent for months has, I think, more to do with the Duggar drama then with Katie's drama. I hope they are still okay. They weren't the most active people to begin with, so I'm sure they are fine without being present on IG.
Ofcourse Lawson is the center of all the stuff of Medic corps. That's how he is. Maybe Nathan quit, maybe Nathan didn't go because he couldn't for wichever reason. Maybe he is there but Lawson didn't feel like sharing the spotlight with his brother...
