6. Tommen Baratheon Was 7 When He Married Margaery Tyrell It's hard to imagine that Tommen Baratheon who has clearly been aged up a few years in the show, is only seven years old when his brother Joffrey dies and the crown is placed on his little head. Could you imagine a seven year old running things while his mom rots in prison? Still, he'd have done a better job than Joffrey. Not only does he have to run a kingdom, but he also had to marry Margaery Tyrell who was 16 years old in the books - a whole 9 years older than him. And she's already been married 3 times. As if that's not shocking enough, we all know that it's only a matter of time before Tommen dies and we're guessing he'll only officially be 8 then - making him potentially the youngest (main) character death in the books so far? Not counting babies, obviously.
