I think that of all the female Maynards, Margot might be quite bearable away from her triplets. And if not, you can order her about because of her training to Instant Obedience. And Lawrie would be an amazing pirate if she were pretending to be someone else. I was thinking of that bit at the start of The Marlows and the Traitor where she's not particularly surprised because of all the films she's seen.
