The other one that was recently found is in regards to Ego and Mantis. In the film, Mantis says, “Ego found me in a larva state. Orphaned on my homeworld. He raised me by hand and kept me as his own.” This comment would explain why she was so loyal to him before ultimately joining the Guardians, but one fan surmised that she may actually be his child after finding a specific Easter egg in the scene where Ego was explaining how he went about his search across the universe. While it was a hidden Easter egg, James Gunn took to his Facebook page to explain it wasn’t the “Big One.”
Whether or not it’s the big one, it was a heck of a find and gives a little more insight into Peter Quill’s father. When Gunn finally cops to what the big ones are, we’ll bring you the info. Until then, have fun searching!
