Warning: Spoilers ahead for "Game of Thrones" season six.

The eighth installment of season six, "No One," ended on a fire note when Arya finally claimed her Stark identity and left the House of Black and White for good. But between the seventh and eighth episodes of "Game of Thrones" this season, fans went on what might have been the most prolific theory spree we've ever seen. Many of the predictions were centered around Arya Stark and how she could survive a brutal stabbing from the Waif.

Tech Insider spoke with director Mark Mylod — the man behind episodes seven ("The Broken Man") and eight ("No One") — to get a better understanding for what Arya was really going through during the build up to this epic showdown.

"For Arya to be successfully ambushed by the Waif, she had to make a mistake," Mylod told TI over the phone. "She had to let her guard down."

Remember, in episode seven Arya was seen convincing a Westerosi captain (with the help of lots of gold) to give her a cabin and safe passage back to her homeland. Arya didn't have her sword, Needle, with her and she didn't seem too paranoid about her surroundings.

Arya had a new, confident look in episode seven. Macall B. Polay/Game of Thrones Mylod wanted to make it clear that Arya is human — she makes mistakes just like everyone else. And her young age is a factor, too.

"We had to set up a situation where it was plausible that a warrior like Arya messes up," Mylod explained. "She allowed herself a moment [of reflection]— and this is where you have to remember that despite what an extraordinary warrior she is, and all the hell and back that she's been through that she's still such a young woman, and is vulnerable and flawed like every wonderful character in the show and every human being on earth."

After securing her passage home, Arya stopped to take in the view of Braavos.

"When she stops to look over the city and has a that moment of reflection ... and she looks towards the great statue in the harbor, she just drops her guard for a moment in a very human way and it almost costs her her life," Mylod said. "And I'm sure that Arya will be furious at herself for that."

This was certainly a costly mistake. Arya is stabbed in the gut — a type of wound other "Game of Thrones" characters haven't survived in the past. Arya's foolishness was just barely outweighed by her ability to think on her feet (literally) and get to safety.

"One of the many things our writers are so great at is allowing our characters to be flawed," he explained. "Nobody is perfect, we all make mistakes all the time, and Arya nearly pays dearly for it. Thankfully her determination to survive is such that she is able to come through it. But it is a really close call."

Mylod was aware of all the crazy fan theories about what Arya (or should we say Jaqen?) was up to in this scene, and found them quite entertaining. "To be involved in something that causes that much of a conversation is really a genuine privilege," Mylod said. "It really is quite extraordinary to be involved in something that causes so much fervor. It’s just wonderful."

So theorize away, "Game of Thrones" fans. Just don't hang too many hopes on those complex predictions.
