Answer:
I would of made the sound deep, somewhat emotional, like with violin or piano in the background, while the dialog played. If the mentor were to push the lead character off the building, I would add some music that was intense, to add onto it, and when the character would start to fall, the music would get deeper and quieter, and make the music cut out as the character fell the rest of the way. If somebody saved the person, like somebody were to save them by grappling onto a building and snatching the person, the music would go up, and be a bit more up beat.
that would be what I would of put if I were to have that same question on something.
I hope that helped you!
