Almost Eternal - updated 11th August

Oh, she knows what she's doing. When she says that she's happy that he's forming 'genuine relationships', she very much means 'ones that she approves of' with people who won't undo all her hard work.

Wouldn't she be disgusted with herself at how similar she is with her own father?

She would say that she's nothing like him, nothing like any of the other vampires, beyond vampire. Which should give you an idea of how deeply she is buried in her own poop, how poor she is at self-reflection, how numb she is. But you're totally right. Her methods are different to her father's (and have varied over the years, I'll just add that in here) but her outcome is similar: she has 'parented' a child who has grown up in fear and isolation, to be nothing but a shell. Lilith suffered for 16 years at the hands of Silas; Caleb's had 300 years of Lilith's experimentation to make him 'safe'. Her mission is the same as it ever was, but her reasons behind it have become lost, somehow.

The further back Seth has to go to 'rewind' the less reliable it becomes. Brains are extremely complicated, non-linear things and no two are alike. Let's leave that there.
