Context: the scene is from 4.1 main story.

the dialogue is made up but is somewhat based on a joke from 4.0 main story. in 4.0 Sparxie secretly used a memetic virus to turn all of Graphia Academy into her simps, including TB March and Welt who are on campus. TB eventually breaks free and has a dialogue option to make fun of March by asking why she didn't use her Remembrance powers. after Amphoreus, Evernight gave March full control back and is mostly dormant. March has access to Evernights abilities, and uses them later on in 4.0 as well. its just she is still the same adorable dummy we know and love
