"You've become quite a nuisance -- you and your friends, the Bogarts -- meddling in affairs that are none of your concern. The time has come for that to end. But I quite forget my manners. How utterly boorish and jejune of me not to introduce myself. You may call me Mr. Sinister."
The events of "When Dreams are Dust" take place after the events ot "Little Boy Lost" from Classic X-Men #41.
It is ironic that Scott Summers' tormentor from "When Dreams are Dust" should be named Nate. Nathaniel is also the real first name of Mister Sinister as well as Scott's future son, Cable.
