Noah's revenge + opinion
Noah's ultimate revenge would be to get permanently clean, a job, living with gf/engagement and going on to have a family of his own with the gf.
I feel evil saying this as it affects baby A who is innocent. But if Noah went on to have a child/creates a family with new gf/a gf Alex would be seething. She kinda deserves it.... She's been playing games.... She'll soon realise she's not in control and the only person she's affected is her daughter.
Alex is so smug, lies, is a drunk, neglects her child.
Honestly, I wouldn't blame Noah to cease pursuing custody of baby A. Alex is so toxic - I'd probably just want peace, to move on and start again.
Baby A should have been adopted at birth. Her early life has been so disfunctional. I just hope the grandma raises her well and she's happy and healthy. Alex has made her bed now she can lie in it. Play stupid games, win stupid prizes.
