Dr. Blanc arrived at Alexander's place alone, late at night, and woke him, Austing, and Mike before gathering them in a room. He stood grimly before them, holding a traveling case. Austing, accustomed to a healthy lifestyle, was the sleepiest of the three. Yawning, he asked, "Dr. Blanc, what's so important you had to wake us in the middle of the night? Don't you need sleep?"

"This is important," Dr. Blanc replied, looking around. "Alexander, is this room secure?"

Alexander nodded knowingly. "Don't worry. The construction team built the walls with special materials to prevent eavesdropping."

"Excellent." Dr. Blanc nodded, thoughtfully observing their expressions. "What I'm about to tell you is highly classified. You must not repeat it to anyone. Understand?"

Austin snapped to attention. "Why all the secrecy?"

Mike, hugging a pillow, sat up, looking alert. "What is it? Am I… allowed to know?"

Alexander and Austing were close to Dr. Blanc; only Mike seemed an outsider. "You stay. You're in the know as well," Dr. Blanc said, nodding.

"I am?" Mike was bewildered.

"It's about the invisible woman," Dr. Blanc said quietly.

The other three looked perplexed.

"What about her?" Austin asked. "Are you saying your analysis is complete?"

Dr. Blanc nodded and opened the case, revealing a document filled with data and records, along with a single sheet of paper. The trio couldn't decipher the data, but the accompanying paper was clear. Based on Rhea's hair and items from the scene, it indicated traces of an invisibility potion. In other words, invisibility was possible.

"What the hell?!" Austin chuckled, holding the paper. "But how is this proof? Why an invisibility potion? How do you even know what it is?" After all, no one had ever seen such a potion.

Dr. Blanc remained calm. He revealed another document. "We conducted experiments using Rhea's hair and skin flakes. We found changes occurred under specific conditions. For example, her hair would slowly become invisible to the naked eye under high temperatures; however, its form and molecular structure remained visible under a microscope. From repeated experiments, we believe the invisibility potion exists."
