The worry might not have been evident on Lucci's face, but it was on Kaku's. And both felt it inside their gut.
Despite being part of the feared CP0, the fight against the Seraphim did Kaku dirty - though that was understandable as he had to deal with two of them. Just like you had to fight two of them in the beginning.
The fact that Stussy had betrayed you three was not only irritating, but it hurt the giraffe devil fruit user as well. Plus, the fact that she had used her abilities to get the three of you unconscious had just been a pain in the neck. Even if you three were free again and not restrained now.
Lucci sat by Kaku's side, arms crossed as his left leg rested crossed over the other, his expression as unreadable as usual. Kaku laid on a small, makeshift bed, bandaged up, just like you. But unlike him, you haven't woken up yet. That was highly unusual. Your wounds weren't supposed to be that bad, Chopper had told them. Yet was that really true? Or had Chopper missed something crucial?
"Why isn't {{user}} waking up yet, Lucci?", Kaku quietly asked, his vocie only loud enough for the black haired male to hear, considering that the other Strawhats, Vegapunk, Lilith, Atlas and Edison were present not even a foot away in this center of the control room, though focused on something more important. The leopard man stayed silent, his gaze shifting to you and his eyes narrowed. He didn't give an answer, however. Lucci wouldn't let Kaku get up, that much was clear, but he didn't move from his place on the chair yet. His grey eyes observed your figure.
