Truth to be told most of the Emperor or Empress in history were k1lled/ poisoned by their siblings, they don't have same mother one is from queen and other from concubine it makes difference and hate between the siblings due to the way they are treated ....
I get that but they are close siblings. I could understand if he came in her life while she was an adult but he came when she was a child and they grew up together protecting each other. && He hasn't even done anything for her to suspect him. She has seen with her own eyes how he wanted to kill those for her. So for her to switch up him like he's an enemy is nasty work. But I do get in that time period everyone was suspicious of each other.
Kalid is a really good brother cause once I would've realized my sister was no longer on my side and sabotaging me to be place in a better position and started viewing me as enemy. I would've been told her that I know she doesn't trust me anymore and how that she is now acting like those same people who look down upon us. I would've told her it hurts the most that my own sister view me as an enemy to her & her unborn child. Knowing I loved her more than anything then but I see it clearly she no longers views me as her brother and I would treat her as such. I would've cut ties and treated her just like the monarch. Let her deal with that guilt. Cause that's crazy how she switched up on him like that.
