Horus is giving a speech to a crowd of civilians, with the Mournival around him as bodyguards, when someone in the audience throws something on the stage.
Abaddon sees it and his battlefield instinct kicks in immediately : he jumps on it like it's a grenade to protect his Warmaster. There's a few seconds of panic, but it is rapidly confirmed that it is, in fact, not a grenade. Abaddon gets to his feet and lifts the object in the air where it unfolds.
It's a bra.
The rest of the Mournival is lucky enough to be able to hide their fit of giggles behind their helmets. Horus is not wearing one. Horus has also been very tense lately and needs an outlet.
He fucking loses it. A full minute of pure, hysterical laughter, unable to catch his breath, all of his Primarch dignity and composure completely gone. Poor Abaddon has to stand there, dying of embarrasment, while Horus desperately tries to get himself together enough to continue his speech.
Obviously the entire thing was recorded by several remembrancers, and very soon the entire legion has seen this moment. Torgaddon will not stop bringing it up, and Abaddon is fucking fuming. They are never letting him forget about it.
