 Mimi Oppenheimer from "A Winter's Love" and Suzy Austin Davidson and Josiah "Dave" Davidson from the Chronos series (Austin family series) all appear in "A Severed Wasp".In addition, Philippa "Flip" Hunter, the protagonist of the early L'Engle novel "And Both Were Young", is mentioned repeatedly in "A Severed Wasp" as a successful and respected artist, who painted a portrait decades earlier of Katherine Vigneras with her young son.The story of Flip, a talented artist who in her youth was initially miserable at a Swiss boarding school (as recounted in "And Both Were Young"), closely parallels that of Katherine Forrester (later Vigneras) in "The Small Rain", and loosely parallels L'Engle's own experiences in boarding school.
