What are the numbers at the end of the conclusion text referencing? Do I unlock those scenarios?
No, scenario 14 does not unlock any new scenarios. There are many ways to arrive at scenario 14, and when you unlocked it, you also unlocked a scenario that couldn't be completed until you completed scenario 14 due to global achievement restrictions. The numbers at the end of scenario 14 are just reminders of where you should go next depending on what your goal was in the first place.
