On the back of Vanya's autobiography is a quote from Gerard Way, creator of the original comic books.
The inscription on Ben's statue reads, "May the darkness within you find peace in the light."
The blurb on the back of Vanya's book ("Extra Ordinary: My Life as Number Seven") reads: "Vanya Hargreeves is well known for her virtuosic skills as a violinist. Less understood is the role she played as one of Reginald Hargreeves' adopted children, standing alongside--but never counted among--the famous Umbrella Academy super kids. This is her story, in her own words. 'An incredible read . . . a revealing portal into the amazing life of Vanya Hargreaves and the life she has lived. I couldn't put it down!' - Gerard Way" The inscription inside reads: "Dad, I figured, why not? V."
The title is also the title of the second issue of the comics.
The plant that Luther waters after he wakes up is an umbrella plant.
