Blyla

Blyla is the het ship between Aayla Secura and Commander Bly.

Jedi Crash
Bly is trying to attach the ship to the Jedi Cruiser, when it suddenly starts to go into Hyperdrive. Aayla tells Bly to shut it down, but he's unable to. She tells him to attach, and luckily they're able to get free before taking the cruiser with them. Aayla goes back to check on Anakin, but Bly follows and tells her that they have a problem. The navacomputer has placed them right in the trajectory of a star.

After the ship crashes on a planet, Bly finds signs of a civilization and shows it Aayla. He asks her where they'll be headed, and Aayla says that they'll try to find the people who live on the planet. Bly asks how they're going to do that, and Ahsoka suggest finding the trees depicted in the drawings.

Fanon
While Blyla is not a popular pairing, it has a decently sized following within the Star Wars fandom. There is a subsection of the fandom that likes to ship the clones that lead their section of their army with their assigned Jedi General. Many fans coming to the conclusion that every clone is just in love with a Jeid. Blyla is typically shipped alonside similar pairings such as Codywan and Rexwalker, though the former more often than the latter. Though Blyla is typically a background pairing in fics, there are still quite a few that depict them in the forefront.

Many portray their relationship as being obvious to all the clones around them. As well as many portraying them as basically being obsessed with each other. Many fans took the ship to the extreme, and just accept the idea that it's canonically happening in the background of the series. Or at least that Bly clearly has a crush on Aayla. Some fans like to portray all the clone commanders meeting up from time to time, and Bly annoying everyone with how in love with Aayla he is. Some will also include Quinlan Vos in their fics, either disliking and being protective of Aayla, or as supportive of their relationship. As many fans portray Jedi Masters as being protective of their former Padawans.

On AO3, Blyla is the most written ship for both Bly and Aayla. There are currently 650+ written works.
