Need more Case lore

They edged us so hard with Case’s backstory and he just dies? I think?

I was so invested in the super soldier lore and how he was experimented on but I feel like he was just used to further Harrow’s story.

Where’d he come from? How did he get involved with the CIA? Why was he chosen for the cradle? How’d he escape and meet Marshall? Why does the rest of the group not know about his history yet Harrow knew?
