Codes explained
Fanfic codes are given by a character's last name. Since both Torres and Tuvok end in T, Tu is used for Tuvok to differentiate them.
Relationship codes are given as Male/Female. In slash cases, the dominate character's name goes first, i.e. Chakotay/Paris, Torres/7.
Commas distinguish multiple character or relationship focuses in a story.
Parenthases () show an implied relationship between two characters.
