Thasper is the ship name for Thalia and Kasper. They reunited at Explorers and sometime in 2022 September, moments seemed to spark between the two of them
In July 2023 the two departed as they left the club and began their spereatae ways.
Thalia had confessed her feelings to him amongst her family and friends, however, it is still not known or confirmed if Kasper ever felt the same way.
Adrien was Kasper's best friend, but it was never revealed or mentioned whether he had feelings for thalia too, creating the cat dog bear love triangle.
