Ghirahim does the Time Warp again!
I actually realized it about the time Groose spend hanging around the Sealed Grounds with ‘Grannie’. I believe when Groose walked though the Gate of Time to help Zelda, he stayed and got busy with a younger Impa due to his rejection from Zelda. Ganon is a descendant of Groose and Impa because she knew that the bloodlines that were connected needed to be continued.
