Voice actor Nick Apostolides disclosed during a podcast interview that he had recorded a one-liner for Resident Evil Requiem that never made it into the final game. During the encounter with a giant tarantula boss, Apostolides had suggested Leon deliver a pun about the creature being an 'itsy-bitsy pain in my ass'—a playful reference to the children's rhyme that would have echoed the character's more humorous side from Resident Evil 4. The line was recorded but ultimately excluded, replaced instead with more conventional quips like 'You are a real pest, you know that?'

The editorial choice reflects a broader creative direction for the character in this instalment. Resident Evil Requiem portrays Leon as more hardened and battle-worn than previously, yet the game retains some comedic moments through his dialogue. Apostolides expressed that the cut line would have been his favourite had it survived the editing process, suggesting a difference in opinion between the development team's vision for a darker protagonist and the actor's preference for character moments that balance tone with levity.
