When everything came out about the Cortexiphan trials in Jacksonville. About how Olivia had been a subject. She wondered did Walter remember the withdrawn child that he and William Bell had experimented on ?

She'd come so far since then. Through everything that had happened , her step father, her Mother's death, the military, the FBI , John….

Looking at him across the lab Olivia sometimes found herself wondering exactly what Walter remembered through the fog of his damaged and drug addled mind.

It shouldn't matter and if it ended up mattering then she would deal with that too, but did he see HER ? Was she still Special Agent Olivia Dunham of the FBI ?

Or was there going to be a momment when Walter, Astrid ,Broyles,….Peter? Would find themselves only able to see the frieghtened young child she used to be.

For people to again only see her as Oliver .
