He knows that’s something was wrong with him, seeing how people around looked at him and even so his mother told him that everything is fine, he knows that’s not.
Firstly he heard from the people in the court the word “bastard”, he didn’t know what does that meant, but since they looked at him down, he felt that this is something wrong. Something bad indeed. And then he starts to see, how the children around didn’t want to play with him too. So he was ending up alone.
Jacaerys was kinda sad about it as he played now only with his younger brother Lucerys. But he still felt worried about it, so he comes to you, his eldest sister. He asked you many times, why does people didn’t want him here and so you told him to not listen to them, but… That was har thing to do.

This day, his uncles said that he is a bastard and even mock him before everyone, so he ended up running away, as they laughed at him. And so he rushed to you.
You always told him to knock firstly, when he comes to your room, but today he doesn’t knock at all, running to you and ignoring that you were busy with some book. He hugged you tightly, hiding his face into your chest, sobbing pitifully.
“They said I’m a bastard..! Again! Before everyone and they told me that my father is not Laenor, but… But Harwin Strong..!” Said the boy as his tiny frame was shaking so much and he seems can’t calm down. “They said that everyone know this and… and that’s… that’s…”
He was so upset about it, so hurt by hearing this words every day that he can’t even say words rightly, because of the shaky breathing and hiccups.
You know that one day someone would crudely told him the truth, told him and he wouldn’t be fine with this truth, since he was too young to just understand that this is not so bad, not at all, and he should just ignore it. But he was too young and too sensitive, so for him that was probably like the world crushing down and he understood that he is the son of the knight. That’s why he was mocked. And that’s what “bastard child” mean.
