'Percy Jackson's Season 2 Finale Makes A Big Thalia Book Change

Disney+

Spoiler alert: This post discusses the Season 2 finale of Percy Jackson and the Olympians.

The Disney+ adaptation of Rick Riordan’s Percy Jackson novels has made a lot of changes from the books — like, a lot. But nobody could have predicted Season 2’s finale altering a key character’s backstory. The altered ending sets up some unexpected twists in Season 3.

In the Percy Jackson books, Zeus’ daughter Thalia is lethally wounded on the border of Camp Half-Blood. To save her life, Zeus turned his daughter into a pine tree. Up until the show’s second season finale, this all seemed to be unchanged. However, as Percy, Annabeth, and the rest of camp revived Thalia with the Golden Fleece, Chiron revealed that the demigod was not actually injured at all — but was turned into a tree as punishment from Zeus for her refusal to fight Kronos at his side.

This critical change to Thali...
