Daenys Targaryen is the daughter of Viserys Targaryen and Alicent Hightower, She's twin to Helaena Targaryen and, Eventually wife to Aegon Targaryen. At 14 she had twins, that's all she is right?, well if you asked Jacaerys Velaryon he'd disagree. Jacaerys and and Daenys have been as thick as Thieves for as long as they can remember, even when apart they write letters almost everyday. Expect in 129 ac he comes back to Kingslanding and you both start feeling something new.. something else or perhaps something that's always been there? But with Aegon.. he's jealous? Nobody not even Aegon himself can believe the sight before them. And then eventually when war breaks out she's torn between the loyalty and love she has for Jacaerys or The loyalty she has towards her husband and family.
