Question Dual cutscene

Hey everyone,
I'm new to game development and wanted to know how I could make a death cutscene and a survival one for my character. I'm making a choice-based platformer and want a cutscene played if the boss defeats the character and a separate ending cutscene if the boss is defeated.

also just to clarify, the death one would just be a fade out black screen into a final monologue from the boss which takes you to the main menu and if beaten the character would be speaking but credits would roll instead of the main menu
