"Master Turtle, can I ask you something?"
"Of course my dear…"
"Why didn't I die last week? Because I'm pretty confident in the fact that I drowned…" Ladybug asked in a shaky voice. "I don't know why I'm still alive… Was it my earrings? And the spirit? Did Tikki save me?"
…
"My, Ladybug, you are a smart one, aren't you! I would believe so. After all, Tikki has the ability to restore a dwindling life force." The Turtle said wisely.
"So, can Chat Noir do the same? Or something different?"
"Unfortunately, Chat Noir possesses a much darker power. The two of you work well together because your spirits are partners. When close together, those effects are nullified, however, when apart, dangerous things can happen. Chat Noir possesses the ability to extinguish a dwindling life force, to end the suffering. But this can be used only once per holder, so there's nothing for him to worry about."
"Are you implying that somebody has already died because of his ring?!"
"I am afraid so. I can't tell you much, for fear of exposing his identity. I would if I could, but I am bound by contract to the spirits, but somebody near Chat had a horrible, excruciating illness that would have killed her anyway, and her life was taken by Plagg. It's not something the spirits or the holders choose to do, it just happens. Please do not tell Chat, if you do end up finding him. It will make him detest the miraculous, and Plagg doesn't deserve it."
