Scar relaxed as soon as Lust did. He couldn't think of an angle to guide his actions from. This wasn't a time for What would Alphonse do? or What would his younger self do? This was unique to him and Lust. There wasn't some 'safe' way out.

He wanted to promise that it would be okay, that he would be here. But he couldn't. He honestly couldn't.

Which was the source of all of this upset in the first place.

Scar had thought about ending it. On more than one occasion during the past month, he had nearly called her, nearly asked her to meet him someplace so they could talk, so he could tell her that this wasn't good for her, that they shouldn't attach to each other or rely on each other. He wasn't fit to be anyone's partner like this.

But neither was she, really. They had to learn. No matter how many times Scar weighed the options in his mind, cutting her off or letting this grow, it was always the former that felt it would only be steeped in regret, especially when one of them was gone. The fear kept resurfacing. What if one of them were gone tomorrow? The thought alone was enough for him to tighten his hold on her, protective and clinging. His own defenses were what kept this back. The only thing, really. But there was no need for them with her. Once it was done, it was done. There would be nothing they could do.

He couldn't bring himself to waste time, anymore.
