A lot of the excitement around Guardians of the Galaxy Vol. 2 comes from the introduction of the pint-sized new Groot (Vin Diesel). Director James Gunn recently talked about the cutie pie, teasing that his size is not the only change to expect in the character.
A fan asked Gunn on Facebook whether or not the Baby Groot that fans will see in the sequel is just the small version of the one they fell in love with in the first Guardians of the Galaxy film. The director revealed that this iteration of the beloved character “does not have Groot’s memories.”
This suggests that this little version of Groot in Guardians of the Galaxy Vol. 2 can be considered almost brand new. While it is possible that the original is still inside him, the fact of the matter is that he is practically reborn with no recollection of everything that’s happened, probably including his bond with the Guardians.
