The Umbrella Academy killed Y/n in 1963 and Five used his powers to hide her body in a different timeline. But the Sparrows found her and now Y/n want revenge.

Five: "Y/n? How...you died in 1963?"

You: "What's the matter, Five? You look like you've seen a ghost."

You grin mischieviously.

Luther: "Is that really you, Y/n?"

You smiles.

You: "Surpriiise family."

Klaus look confused and surprised, Five and Luther too, Diego grin and cross his arms, Allison stay speechless, Viktor too.
