Checking only the face
Several tells live in audio, night vision, visibility, size, or another room. Use the visitor-specific clue category.

Quick answer
What to do now
Do not search for one universal sign. Match the visitor to the reported clue type, compare direct view with CCTV or the relevant room, and reject only when the current warning sign or explicit threat matches. If the clue is incomplete, recheck.
Step-by-step
Follow the current route
- 1
Start with the visitor's story
Listen for the request and identify the matching visitor or alias. The story tells you where to look next: the backyard for Dog Man, the parents' room for Cat Woman, the kitchen for Water Guy or Fireman, or CCTV and night vision for several appearance-based encounters.
- 2
Compare direct view with CCTV
Some reported tells are contradictions rather than obvious monsters. Break Up Girl may appear to grin on camera while crying in direct view; Lost Child may appear abnormally large; Ballerina may stare at the cameras; Homeless Man may not appear on CCTV at all.
- 3
Use night vision and audio when the clue calls for it
The FBI Agent's report depends on a night-vision appearance change. Wifi Kid, Homework Kid, Party Girl, and Gym Bro depend on typing, voice shifts, distortion, or an unnaturally high voice. Repeat the check before treating a brief sound as conclusive.
- 4
Check the house for story evidence
A dog, cat, water problem, or fire claim should be compared with the relevant camera or room. Environmental evidence can confirm that the story needs attention, but current sources do not always provide a separate normal/anomalous pair.
- 5
Fail closed on incomplete evidence
Cat Woman, Drunk Girl, Angry Neighbour, and Friendly Neighbour have incomplete or low-confidence decision evidence in the currently checked public guides. Do not convert that gap into an allow instruction. Repeat cameras, voice, story, and room checks or consult a newer source after an update.

Common mistakes and recovery checks
Assuming no tell means safe
A missed or undocumented clue is not proof of a normal visitor. Return to the cameras and environment.
Using an old list after an update
Visitor behaviors can change. Compare the checked date with the current Roblox update date.
