Fanon
While wasn't official ship in Gundam 00, Locktie is one of the most popular and memorable ship in Gundam 00 fandom. The Gundam 00 fandom is quite divided on this ship, mostly about Tieria sexuality and how he see Neil. This ship has rivalry with Lockset in platonic-side and Lockfeldt in romantic side.
 * Some fandom believe Tieria only see Neil as his best-friend or more looks like a brotherly love due to Neil big-brother figure side to the other Meisters. Fandom point out that being Innovade, Tieria has no concept about sexuality or any romantic relationship.
 * Majority of fandom believe Tieria has romantic feeling to Neil. This evidence become more strong In episode 8 of season 2, where Ribbons point out that Tieria let Lockon get too deep into his heart  and his reaction after Ribbons mocking Neil death is similar how someone get pissed when the some person mocking their lover in front of their face. The fact that Tieria's sexual identity is also brought into question - both physically and emotionally - in episode 8 is  surely  pure coincidence. Unfortunately, beside any foreshadowing that the writer intentionally put some gender-queer element on Tieria's character, we never know if Neil has same feeling with him too or he just see him only as comrade.

Trivia

 * The 1st opening of Season 2 show Tieria is seen watching over Lockon's Gundam in battle and, at some point, the focus on an increasingly despaired-looking Tieria's face is framed in almost  exactly  the way a typical Love Interest's face would be.
 * In Newtype magazine 2009, it's state that Tieria almost never associated with any other female character.
 * Lockon can clearly see the weak heart beneath Tieria's "strong" facade.
 * There are possibility before Tieria meet the Innovator, Lockon already know that Tieria is not a human judging from most of his statement is about to make Tieria try to act like the other his human's comrade.
 * Tieria's character has reference about gender-queer :
 * In official booklet, Tieria and all Innovade (except Anew Returner) has no biological gender. Most of Innovade have androgynous appearance, which making it's so hard to guess their real gender.
 * Nadhlee Gundam is reference to Nadleehi . Nádleehi is a social and, at times, ceremonial role in Diné (Navajo) culture- an "effeminate male" or "male-bodied person with a feminine nature". Which is fit to refers a feminine Nadhlee Gundam inside masculine Virtue Gundam body.
