I agree... I dont think she will leave him cause she doesnt have anyone in line to raise her higher.
The only way they end is him coming home. I think he already may be heading down that path having been part of that interview. He was not happy with all that and it only takes one moment to realise.
The true question is will she let him travel alone?
He'll leave, like I said in my other post his body language has changed towards her, he seems like he's disgusted. She's clinging to his hand and when he steps away she moves right in, she knows her time is up.
Reason why they moved to the states to try to get him to see her in a "better" light but it backfired and this is her trying weasel her way back in!
Them dating was a sham, the marriage was over the same day it started.
Luckily there's guards at the palace for a REASON to keep out the mentally deranged peasant!
