   Summary

   Aegon had loved the idea of having a soulmate, until reality came crashing down on his head. His sister wouldn't wait for her ascension to the throne to kill him, not once she knew, and Aegon wasn't so sure he wouldn't welcome the execution rather than deal with his own mother.

   Jacaerys. Of course it was Jacaerys. The gods must truly want him to suffer.

   Tags updated as I go, per usual. Pause Points now labeled in the end notes for those binge reading. :)
