Unfortunately, at this time, we do not know who the 8th Nightblood was. There may be clues, but nothing is certain. Most likely, it will be revealed either this season or next. As for Costia, it is most likely not her? But that is only an educated guess because Costia was said to only have been killed because Nia (Queen of Ice Nation), kidnapped her when she found out they were lovers in order to get information for her. When Costia had no "secrets" to give, they beheaded her and sent her head in a box to Lexa. From what we can tell at this time (as of Season 3, Episode 7), most likely all others have to die before the next Heda (Commander) is chosen. However, this is not yet confirmed.
