He always wonders what would it be like if Valentine never poisoned him. Would he grow up with love, laugh and normal like Clary be or maybe he'll be allowed to dream, to have one eventually. But he will never know, he thought, because simply of one thing, he is the demon child.
The moment Clary ends him, no, Sebastian, it was the moment the true Jonathan Morgenstern been born. Five minutes, that's all he got but it better than none. He should thanks to her for that but he never has the change, you know, he is being a little busy with all the dying thing here.
He thinks to himself, dying it a good thing. It not just dark for internity like someone said, there is light here, and it so warm that Jonathan has never felt before, not that you can felt warm when there is demon blood run throw you. And safety too. He doesn't know why but if this is dead he doesn't want to live for even a second.
The moment he realizes he's not dead is when he hear of a lullaby, so soft and gentle and cover with love and all the best wish from a women that only then and till then he realises he was covered in water, wet and warm. But he doesn't mind at all. He guesses it was the after live shit people always talking about. So that meant he is being pregnant for all over again, lovely. He don't care why or how he still remember, the only thing he cares is if his parents is a better parents than the last one, considering that the last family he has, well, the father turn him to a freaking walking laboratory animal, the mother thinks he is an abomination, his little sis kill him, his adopted brother try to kill him and, well, it didn't end very good.
But the god must be a bloody bastard that loves to make joke or really hate him because when he open his freaking fetus' eyes he sees a freaking glowing blue-ish liquid is running throw the placenta that connects him to his mother and no doubt is was demon blood so now he have two option fight it or let the Sebastion part kill the Jonathan part again.
In the end, he has been born and everything change in a way that it should have been years ago.
