Serena Williams asks fans a very specific question about 'Avatar: The Last Airbender’

Serena Williams may be one of the greatest athletes of all time, but you can’t be an expert at everything.

So the tennis icon crowd-sourced a question she had about a little show called "Avatar: The Last Airbender."

"If the original benders were the sky bisons, badger moles, and dragons; how does that tie in with Avatar Wan when the lion sea turtle gave all the people bending power?????" she tweeted.

That led a user to state that "he only bestowed the gifts to the avatar, not to each nation and the rest of the nations learned from the animals."

He went on to speculate that the animals were most likely given the bending gift by the lion sea turtle.

But this is Serena Williams we’re talking about, so she volleyed the ball back into his court.

“remember a lot of the people left the lion turtles with bending powers," she responded. "They decided to live off the turtles and make a life for them like Wan did."

Asking if the sea turtles gave them all powers, Serena admitted, "I'm really confused."

And so were we. But someone else clarified that the lion turtles gave humans bending powers: “But humans learnt to master it from the animals (and the moon for water benders).”

Still confused, Serena asked if humans had the power first, leading the original user to the matchpoint.

“The animals all did and developed it themselves," he said before going on to note that the lion turtles “opened the bending chakras” in humans, and the animals taught them.

And it wasn’t lost on the guy that he was tweeting about Avatar with, in his words, “TWEETING WITH THE GREATEST FEMALE ATHLETE OF ALL TIME.”

In the end, Serena got the answer she was looking for -- but if you’re feeling more like a *lost* Airbender, that’s probably okay, too.
