Kim really deserves her own post as it is A LOT to unpack.
Kim had two children before Jamal. Jamal believed he was an only child.
Kim pretending to be Jamal, catfished her other son until she couldn't keep up the lie and had to confess.
She got them both together and revealed she had yet another child, a daughter.
In the entire situation, it is about "her" and not her children's feelings. she simultaneously uses her children to process her emotions through. Centers herself as the victim in the situation, because she feels bad for lying and keeping secrets. Then proceeds to urgently speed past the topic into trying to find her daughter. It is very selfish.
