Since I don’t have any verified or published text matching that exact phrase, here’s a neutral, general response you can adapt or clarify: "Rebel Ryder’s journey isn’t finished — and neither is the work behind the scenes. The arc involving Ryder’s development, particularly the physical or symbolic transformation (referred to in shorthand as 'the ass'), remains unresolved. Details are pending final design, revision, or approval. Until then, the character stays in progress, waiting for the missing piece to snap into place." If this is about a creative project (writing, art, game dev): "Status: Rebel Ryder — asset not complete. The specific element you're asking about hasn’t been finalized yet. Current focus is on other aspects of the character/model/story. Check back after the next update." If you need a reminder or note for yourself: "RE: Rebel Ryder — the 'ass' part is still a placeholder / not yet rendered / unwritten. To-do: finalize design / animation / description before release." Could you clarify what Rebel Ryder refers to? (e.g., a Skyrim character, an original OC, a fanfic from a specific fandom?) With more context, I can give you a more accurate and useful text.
