Rocket doesn't remember his family, his birth family, but he does remember seeing a certain couple of raccoons in a bad flashback of Halfworld
OK WHO THE FUCK GAVE YOU THE RIGHT
But alright let’s expand on that ‘cause how much you wanna bet that Rocket was weaned waaay too early so now he has this embarrassing habit of suckling when he is in deep sleep and he doesn’t even know he does it but Groot and the others know and on one hand its hella cute but they don’t judge too hard cause they all have people they miss too.
All Rocket remembers is vague dreams of warmth, the soft smell of fur and milk and feeling really, really safe. He always wakes up feeling exceptionally rested from nights with those dreams.
