At the end of the second season, the Hargreeves siblings found themselves in an alternate timeline where The Umbrella Academy was now the Sparrow Academy.
What was even more alarming was that they found in this world that their dad Reginald and their late brother Ben (Justin H Min) were both still alive.
Along with the return of these two characters, there are going to be some new faces welcomed to the cast.
These will be the Sparrow Academy members Genesis Rodriguez as Sloane, Justin Cornwell as Marcus, Cazzie David as Jayme, Britne Oldford as Fei and Jake Epstein as Alphonso Hargreeves.
