VIDEO : 'Guardians of the Galaxy Vol. 2' Cut Scene Reveals Family Ties

Marvel fans unraveled a major Easter Egg in Guardians of the Galaxy Vol. 2 that could confirm two members of the team are actually siblings, and more compelling evidence has come to light since. One fan pointed out the mural of Ego, Star-Lord's father, who appeared to be with a woman who appeared to be of the same antennae'd species as Mantis, implicating the two Guardians are brother and sister. Actor Jennifer Sharp said last year that she filmed scenes as Mantis' mom in a post on social media.
