This is intended for ch.1 and further.

• Yes. (Question: Should I be hyperbolic?)

• He and I are old news. (Question: How should I answer?)
  
• It’s nothing special. (Question: Oscar: "How'd that visit go?")

• During the investigation on the desk, you must discover a dead parasitic fae by hovering the blacklight on top of the coin until it turns into a burnt-textured coin with smoke, and then keep hovering on top of that coin until it turns into a dead fae.
  
• Yes. (Question: Is there faerie involvement?)
  
• Warrior. (Question: Which one is it?)
  
• (Question: What is the evidence?)
  - Third victim’s blood sample
  > The blood is faerie blood (Question: How do the purple traces, or parasitic magic as you say, have a part in this?)
  - Dead fae
  > A failed transformation magic (Question: And how does it end up here?)
  - Ring
  > It’s a part of transformation magic (Question: But why does it glow purple as well?)
  
• Warriors replaced victims with changelings, then killed the changelings with ossification and hallucination spells. (Question: Give it to me straight — how do you figure the murders were carried out?)
  
• Warriors are targeting people blessed by the scribes. (Question: Based on your investigation, what could be the rationale behind the warrior faeries' actions?)

Discover additional clues using the instructions below. This information appears at the end of the deduction phase if you have enough accuracy points, or in the form of the MC’s thoughts during the second investigation.

Information Appearing as the MC’s Thoughts During the Second Investigation
Most evidence items shown to Florence/Oscar will result in additional thoughts in second investigation, sometimes depending on the information from the character being interviewed.

Information Appearing in the Deduction Phase
Blood: Interview Florence, show her the fourth victim’s blood sample.
Occult: Interview Oscar, show him the crime scene photo of the first victim.
Makeup: Interview Florence, and show her the makeup.
