John Egbert/Dubiously Canon

In Pesterquest
John Egbert first appears in Volume 1: 'Magic is Fucking Real'.

In The Homestuck Epilogues

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

At some point after arriving in Universe C, John began having dreams about Lord English's destruction of the Furthest Ring, and the ghost army being sucked into the Green Sun's black hole. After calling Rose for advice, he visits her apartment, where he learns about her transformation into her Ultimate Self and gains a new understanding of Canon. Rose tells him that he needs to travel back into the Furthest Ring and help defeat Lord English in order to maintain his timeline's canonicity.

On a picnic in the Carapace Kingdom, Roxy and Calliope, who are hesitant about John's mission from Rose, offer him either meat or candy to eat. What he chooses to eat influences his decision about his mission. After eating the meat, he decides to try to defeat Lord English: after eating the candy, he decides to stay on Earth C.

Meat = john
