Reborn's Real Name Challenge

Reborn's real name is never revealed in canon; the fandom uses 'Renato' a lot, but there's a distinct lack of fic about Reborn's backstory and name. There are many unexplored possibilities! There are a few different ways this could go:
1. If Reborn's real name is Renato Sinclair:
1a. Why did he choose an alias that's just a translation of his real name? Is he just really bad at coming up with aliases? What happens if someone notices the connection?
1b. 'Renato' is Italian and 'Sinclair' is usually Scottish; how did that happen? Is the world ready for Reborn in a kilt?

2. If Reborn's real name is something else:
2a. Is it really weird or embarrassing? How do the other characters react to it?
2b. Is he related to another character? How does that affect the storyline?
