The whole relationship of Worf and Alexander is written so horribly. I don´t get why they even put it in the show. Just to make otherwise cool Worf look like a total asshole every once and then? They didn´t even know what do with Alexander after introducing him which resulted in every single Alexander episode being a milk dud episode. K’Ehleyr on the other hand, who was a real interesting character with much potential, was killed off super fast. I just wish Worf never had a son T_T
