Good, there was a sense of clarity in Mars' eyes, which meant she'd fight and not just wallow in self pity and let herself be killed. That was not the teen whom Venus had chosen to be her second. It was the one who was willing to fight until her dying breath, with fire and drive. The one Minako had known she could trust with that weight and the one she had trusted with her secret. This was the Mars she had chosen and like hell was she about to sit back and watch her fade away. They were soldiers, they would always have to fight. There was no peace for them, even though they were no longer in the Silver Millennium. They had been born again to fight and they would always be born to fight.
Was she worried about Mars' physical state? Of course she was. It was obvious the other teen had been through a fight. But the fact remained that she couldn't give up and let herself be killed. She couldn't let that fact keep her from showing her true potential. And there it was in decimating one of the demons at hand. Good, now it was two on two as Serenity obviously couldn't be counted on to fight. There was no threat to her precious Endymion so of course she wouldn't fight or care.
With Diamond focusing on her, Venus spun and winked to Mars before grabbing the belt around her waist.
"Venus Love Me Chain!" With that, the chain of hearts lashed out at the demon, wrapping around the shell and throwing them into the wall before she channeled a Crescent Beam into her Tambo and shot it point blank at the demon, who vaporized as Zoicite had when she had killed him the first time when she made her appearance as princess.
