The Women and the End of Houses

[Winter Blues]

Anyone else notice how the Women on Game of Thrones are extinguishing major historic houses left and right? 

Sansa ended the Bolton line;

The Sand Snakes ie, Bastards, ended the Martell line;

Cersei ended the Tyrell line;

Brienne ended the Baratheon line;

Arya ended the Frey line; and

Dany ended the Tarly line.

i wonder if this is done purposely by D&D? 

 

[Meera of Tarth]

Maybe it's because this is how Woman on Top works, women empowerment and these stuff.

But Gendry and Sam could still continue their lines if some necessary things happened.
