I’m finding it really funny that she treats a random stranger who looks like her dead child better than she treats a child she raised alongside her own kid, who also loved her kid, and who has a personality very similar to said dead child. And yes we can argue that because mc left she didn’t have anyone, but cmon. She could have easily found mc if she actually cared enough. She’s just choosing the easier option here by adopting someone meek and mild and willing to be adopted rather than atoning for her mistakes.
