Myrtle's backstory as Agent 28 is revealed organically through Lincoln's excitement and the plot, providing in-story justification for her competence without forcing modern framing. The series background includes incidental diversity and an established gay couple among supporting characters, but these play no role in the movie's narrative, characters, or themes.

Reviews note Myrtle as an older female spy 'breaking age and gender stereotypes,' yet this remains a minor empowerment note in a classic adventure setup rather than activist messaging or central conflict. No evidence of race/gender-swapping established characters, explicit social justice lectures, identity politics as plot driver, creator statements prioritizing inclusion mandates, or audience backlash labeling it 'woke.' Family teamwork and Lincoln's spy fandom drive the story in traditional genre fashion. As children's media, the stereotype note receives some weight but does not elevate beyond incidental elements that do not shape the core premise or emotional arc.
