In my opinion I feel like there’s a reason we didn’t see his void scenes. With Bucky we’ve already unpacked his trauma and his entire healing process. He’s moved on from that now and he’s going on to better things hence the congressman job. If we saw his void scenes it would have been a bit redundant for his character and his storyline. I do agree that he should’ve gotten more screen time though
Bucky makes sense but we still could’ve gotten a quick montage to see how he got to Bob. It’s really Ghost and Red Guardian that got stripped of Character development. I also would’ve liked to see a few more void rooms from Walker. Like some of the PTSD missions that he and Battlestar were discussing in F&TWS.
