Hachimaki's Dilemma
I thought Hachimaki would have some thoughts after meeting with Claire while she's in prison. He'd spent some time with Tanabe, but I can't help but think the reality of what had happened between Ai and Claire on the moon wouldn't have truly hit him until after he'd talked with Claire. This may modify the timeline slightly, but, as it was pretty wide open, I'm not sure it even does that.
Hachimaki'd used his status as a Von Braun crewman to access an EVA suit on the station. In reality, he didn't need the practice as he'd claimed; he needed the time to think, and space was the best place for it. He'd been careful to turn off all but the emergency communications links. After all, he really didn't care to share these thoughts with anyone. He clipped the tether on and floated away from the station.
"That idiot Tanabe, what was she thinking?" he shouted, safe in the silence of space. "Seconds from dying! Dying! She says she'll make a full recovery, but is that really even possible? Idiot!" He hadn't shown it in front of her, but seeing her in that wheelchair had terrified him. He'd nearly lost her! His 'friends' at Hanko had carefully spared him from many points of even the big picture. He'd had a mind to tear into them for it, but then he'd decided he'd have probably done the same thing, so he'd let it slide.
He still was in awe of what she'd done. It wasn't just that she had, for all practical purposes, died to save Claire, but that she'd carried her that far itself was amazing. In point of fact, he was more than a little amazed by the woman. That was a good portion of the reason for this jaunt in space: he was scared. Scared! He was scared because he didn't think he was worthy of her. He wanted her. He certainly wanted her to be his wife, but how… How could what he was and the little he was doing be worthy of her courage and love? He certainly hadn't done much to earn it. In fact, for far too long, he'd pushed her away.
Hachimaki shook his head. Such timidity just wasn't like him. She was coming to the station, and it'd be his only real chance to propose. Whether he'd succeed or go down in flames, he was going to press his case with the woman he loved.
I was extremely impressed with the amazing way Tanabe laid her life down to save Claire even after she knew what Claire had tried to do, and it marks her as perhaps the strongest woman I have seen in anime. While I don't know anyone who's done quite that, I do know women that demonstrate that kind of strength. Would that I'll ever be worthy of a woman with that strength of character.
