A Game of Thrones loving dad fainted during a dragon egg gender reveal upon discovering he's having ANOTHER boy. Marvin Holden was hoping for a little girl to join his three sons, but it was a case of the Brother of Dragons when Marvin and his family rubbed the color-changing dragon egg on May 2. Joined by wife Amber and their sons Gavin, 10, Trevin, 8 and Drayvin, aged 3, the family rubbed the egg, which changes to either blue or pink when heated, revealing the gender of the child. As the egg turned to blue outside their home in Texas, USA, one onlooker shouted, "Ooooh, another little boy!" before Marvin hit the deck. A former navy corpsman, Marvin's collapse was caused by a condition called cataplexy, which, along with narcolepsy, resulted in him being discharged from the Navy in 2016. Cataplexy causes sudden muscle weakness and is impacted by emotional changes caused by the likes of laughter and terror. The surprise of the moment was enough to trigger Marvin's cataplexy and cause him to collapse - something Amber's cousin, Elvira, who purchased the egg, said she has done many times before to him. According to Elvira, other medical issues for family members have meant that this was the first time the group had been together for such a reveal.
