Thalia is Paloma Kwiatkowski
According to Imdb, Kaya Scodelario is rumored to be playing Thalia Grace.
They never outright said it but they hinted towards that twice in the series.
Yes, I have e-mailed Rick Riordan, and have found that Thalia is indeed going to reappear she appears with Artemis
Thalia's mother, who is named Sally Jackson, is from New York City. She is a mortal woman and a significant character in Rick Riordan's "Percy Jackson & the Olympians" series. Sally is known for her warmth and resilience, and she plays a crucial role in Thalia's and Percy’s lives.
Thalia has electric blue eyes, black spiky hair, and freckles.
Thalia likes Luke as a friend, but that quickly disappears when she finds out that Luke is evil.
Thalia's mother was a celebrity who wasn't really too famous. She died in a car accident when Thalia was still a pine tree. Her last name was Grace, but her first name was never indicated in the series.
Thalia does not like anyone in the Percy Jackson series. Since she had taken the oath of the Hunters she can never marry or fall in love with a male. However, it has been hinted many times throughout the series that she liked Luke until he went bad. It has also been rumored that she and Luke had a romantic relationship while battling monsters together when Luke was fourteen, and Thalia was twelve because they ran into the Hunters and Zoe Nightshade asked Thalia to join the Hunters, but she said no because of Luke. But Thalia has not confirmed that she likes anyone in the Percy Jackson series.
In the Percy Jackson and the Olympian series the only child of Zeus was Thalia Grace. But in the Lost Hero series (spolier alert) there is another one named Jason.
the 2010 Percy Jackson series is about Percy being lost and Annabeth looking for him. She and many others including Thalia there are new characters in the end one of the new characters knows where he is. i couldn't put it down hope this helps:)
Percy's cousin who is the daughter of Zeus is Thalia Grace. She is a demigod and a prominent character in Rick Riordan's "Percy Jackson & the Olympians" series. Thalia is known for her strong personality, bravery, and leadership qualities, especially as a Hunter of Artemis.
Assuming that this in reference to the Percy Jackson series, the Lieutenant of Artemis's huntresses was at first Zoe Nightshade, but after she died, Thalia Grace took over.
