"He was a lot of things to me" "The only conclusion was love"
Right? So even if Neal did go back to try and convince her now…what could he even tell her? There’s no way he could explain how he let her go because of the Curse and try to get her on side enough to forgive him and be willing to listen to him because he had a good reason for it…if that Curse isn’t even a thing any more.
Especially because all he is right now is the guy who sent her to jail. They’ve erased Manhattan, SSTTR, ect.
