Multiple real children inhabit Lucia Mar's mind, with control switching instantaneously and an external dog able to override them remotely.
Florin senses more than one person inside Lucia and believes most are children. One, Jill, briefly speaks coherently and asks for her mother before an abrupt change restores Lucia's hostile swagger, accent, posture, and voice.
The controlling dog can seize the body from afar but only in short bursts. Alexandro is also connected to the mechanism. Florin concludes the coalition must capture or destroy the dog rather than kill Lucia, because removing it will end the remote control and allow the trapped children to be addressed.
Several child silhouettes layered inside one adult crawler body, with a distant dog pulling short control strings.
The revelation reverses Lucia's objective from elimination to rescue and shifts the target to her dog.
