In the very first episode of Game of Thrones we see all of the Stark children get a pet wolf.
During the TV series, these wolves have played a semi-important part in certain situations and have every time indicated that the wolves protect their master.
- Arya's wolf bit Joffrey to protect her
- Robb's wolf attacked Lord Umber and bit off 2 of his fingers
- Jon's wolf has come to his aid in battle a few times
Sadly, we also see Stark children lose their wolf without the character being killed.
Is there a meaning to/behind these these losess or is it just to make us feel bad?
