Rose: ‘Can I get you anything?’
Alt-Jackie: ‘Yeah…the last twenty years back.’
In Real-Jackie’s timeline, Pete has been dead for roughly twenty years, depending on how old Rose actually is now. But by the end of the show, she has Pete back (a version of him, anyway), her daughter back- everything she ever wanted.
Rose did give her the last twenty years of her life back!
I swear all these thoughts wil be put in coherent essay format soon.
