Listen to three groups at the blue Alley door. Record their counts, repeat them with melee hits, then listen for a new pattern. You must answer three different patterns.
Record all three groups you hear. This helper records counts; it does not listen to your microphone.
If the door rejects a reply, listen again and correct the counts. A new pattern needs a fresh observation.
