in one of Lemony’s appearances in the movie we can see a portrait
going back to aunt Josephine’s part we see a picture too, where she shows herself and Ike (and we can also see uncle Monty), but look closely
we have Kit, and Jacques is holding her.
the other man is probably Lemony, since his face is always a blur
plus, take a look at the woman in a pinstripe suit.
Esmé Squalor, maybe?
