Rose Lalonde/Dubiously Canon

In Pesterquest
Rose Lalonde first appears in Volume 2: 'Something Beyond The Sky'.

In The Homestuck Epilogues

 * From the reader's point of view, Rose's story in The Homestuck Epilogues picks up from where her Canon biography ended.

At some point after arriving in Universe C, Rose became ill and began having visions relating to her transformation into her Ultimate Self. She related some of these visions to John, informing him that he had to travel back into the Furthest Ring and defeat Lord English in order to maintain Canon.

Rose's life on Earth C differs depending on whether John follows through on her mission or not.
