Beetlejuice 2‘s Lydia Deetz reveal may retcon an important detail about Winona Ryder’s character 36 years later after the figure was introduced. The Tim Burton sequel seems to be retaining the overall tone of the original film alongside its central cast, albeit with many of them, including Lydia Deetz (Ryder), having aged and changed offscreen. Despite this, some aspects of her original characterization seem to have remained as well as been passed down to daughter Astrid (Jenna Ortega).
