Lilou didn't regain consciousness, even when Samael had stolen the core from her. According to Alexander Bloodfang, it was more likely an unconscious decision she made. Also, with her pregnancy on the table, it was better for Lilou to stay unresponsive, as it would be painful because of being human with a vampire in her womb. Turning her to a vampire now would mean killing the child.

After the search, the causality Lilou left wasn't as devastating as what happened a month ago. She injured a few while others bled out. One could say she didn't mean to kill them, but one could also argue she simply wanted to give them a slow death. Thanks to Rufus and the third squadron, many knights had survived. Even so, their view towards Lilou and the royal family grew more hostile.
