I'm writing this story where a good friend of the main character gets kidnapped by a clan of sapient Gorilla-like creatures. In order to find where they are keeping him captive, the MC decides that the only way to know for sure is to capture a gorilla-like creature alive and interrogate it to find answers.
The following is true:
The creature is about twice the size of a Gorilla, "Gorilla beringei graueri," and is roughly as intelligent as a 12-year-old human pre-teen.
The main character has special ops training and has access to anything that can be found in an average American kitchen.
The gorilla must be reasonably contained to the point that it could not break free following several hours of intimidation/interrogation.
The creature cannot be reasonably harmed during its capture.
MC is not a human, but an elf. She has the same general build and capabilities as an adult human female but is 3 feet tall
The gorilla has no knowledge of the original trap, but will actively be pressuring the main character before the trap is sprung.
