Grand academy 2: val

How do I get a good ending with Val? Near the end, when you pursue them into their world, you get three options:

  1. Take them back to academy via persuasion
  2. Force them back to academy as prisoner
  3. Settle things (I think thats fighting them?)
  4. Fire the gun and trust in your destiny (??)

How do you get the gun for the fourth option lmao? I think that’d be a more interesting ending than taking them back to the academy.
