41. You ARE the Father!
One of the biggest fan theories associated with the A Song of Ice and Fire series is that Aerys had an affair with Tywin’s wife, Joanna Lannister, taking her virginity before she married Tywin. The result of this affair, depending on who you ask, was Tyrion Lannister or the twins Jaime and Cersei. Given the twins’ propensity for incest, Cersei’s hints of madness and egomania, and Jaime being told by his aunt that “Tyrion is Tywin’s son, not you,” most find it fitting if the twins are secret Targaryens. This, of course, means that not only was Aerys killed by his own bodyguard, but his own biological son!
