User blog comment:Aithusa07/Mordred Is a Dragonlord. Or is he...?/@comment-141.0.10.7-20120224094036/@comment-4814726-20120225020304

TECHNICALLY(thats substitution for italics not being mad), Kilgharrah wasnt the last of the dragons since Aithusa was there the whole time. Because TECHNICALLY the EGG has a live dragon inside it, so that dragon is alive, not dead, so it is effectively a dragon which exists same as Kilgharrah. So TECHNICALLY, there were always two dragons, just no one knew about the other one until S4 ep 4.
