would you say terezis seer powers are more developed than roses?

They’re a different set of powers so it’s sort of hard to compare- It comes more naturally to Rose having reached God Tier, but Terezi actively uses and reaches out with them more. And in a way, Terezi has problems with herself, that she tries to solve with her powers, where Rose has problems with herself, including with her powers, hence her breakdown with Rosesprite. They two have their deeply rooted issues, and both of them have a version of themselves they consider to be better with their powers than they are.

The Seer gals need a big hug.
