The answer to this question depends on which character's death you're referring to. Here are a few possibilities:
1. The Hound
- In the books, the Hound, a fierce and loyal companion to Arya, is believed to have died protecting her from the Brotherhood Without Banners.
- He is later revealed to have survived, but his fate in the books remains ambiguous.
- In the TV series, the Hound's fate is different, and he survives various encounters with Arya, ultimately parting ways with her.
2. Syrio Forel
- Syrio Forel, a skilled swordsman and Arya's first teacher, sacrificed himself to protect her from the Gold Cloaks in King's Landing.
- Though his death is a pivotal moment in Arya's journey, it's important to note that Syrio's sacrifice was not directly to save Arya from a specific threat, but rather to protect her from harm during a chaotic situation.
3. Other Characters
- While these are the most prominent examples, other characters can be argued to have indirectly contributed to Arya's survival.
- For example, the deaths of her mother, Catelyn Stark, and brother, Robb Stark, may have indirectly motivated Arya to become more resilient and survive her own perilous journey.
Ultimately, the answer to the question depends on the interpretation of "save" and which character's sacrifice is considered the most significant in Arya's journey.
