Loved the characters and the story was compelling but too many things were magic wand-ed away at the end - Jackson’s entanglement with his past, Oliver’s relationship with his parents, not to mention the whole Kay situation and how she never posed a problem again after he left. 

Also, the descriptions of the whole train/cave thing left me extremely confused as well as the time lapses and his daughter’s age not adding up. I was all [insert confused lady doing math meme]

Not sure I can forgive Jackson as easily as Oliver did for 1) leaving him AGAIN, and 2) not getting off his ass to find Ollie AGAIN even though he could easily have contacted Gray to find him.
