I feel like I missed something between new order and new collosus.

I finished new order a couple days ago and now I'm playing new collosus. From what I saw and understand, Caroline and BJ are resistance battle comrades and she held a leadership position. And I understand they had a friendly relationship, as stoic as bj is in general. But ever since the beginning of Wolfenstein 2 and bj takes her suit after almost dying. But him talking to her "spirit" as if she's with him or on the radio has me a bit confused. I understand his impending death has him in a delecate mental state. But I feel like based on the nature in which he talks to her ghost, they were much closer than I got the impression from playing the last game.

For a while I kept thinking he was talking to his pregnant gf and I had just gotten the names mixed up.

Did they have a closer relationship than the one I saw in the last game?

I'm really liking the second game. The gameplay is ok, not great, but the lore and world building is top notch.

The only other game I've played in the series is the original. The one you can play in the galley.
