[AN: This was put together by the user HarkenEliwood. He did a great job gathering all of the information in one place. I just corrected the list a bit here and there (check for 'AN'). So thank you, Eliwood. You saved me quite a bit of tedious collection work.
Also, the list is not in chronological order for Sean's lives. That order hasn't been finalized. If I'm being honest, it probably never will be. And don't take the descriptions as ALL Sean did in that life. It's mostly just how the specific life came up in the main story.]

2 - 69th (current) life : DC : is a barman
