PROMPT: "During the events of the movie, Groot makes fast friends with all the other Guardians (or just one in particular, if it suits you, Filler). Rocket becomes jealous when he realises that Groot is no longer his special friend and his alone. Could be romantic/sexual jealousy or just some bromance, up to you."
FILL: Rocket/Groot, Rocket is jealous
