Synopsis for "A Tale of Two Islands"
- Synopsis not yet written
Utopia. The sanctuary for mutants to escape a world that wants them extinct. So is it the ideal home for X-Factor? That's what Cyclops believes when he invites the world's only mutant detective agency to relocate to their floating island retreat and take up residence there. But will Madrox and his team believe that it's the best place for them? What old faces will pop up, and what old acquaintances will be renewed? And will there even be a Utopia left when the mysterious Crone shows up and threatens to bring the entire place crashing down into the Pacific?
- It is unclear when this issue takes place since, in the main X-Factor series, the group isn't assembled the way it is here until issue #206 and events from this issue are mentioned in issue #205.
- Dazzler and Longshot briefly rekindle their relationship.
- Boom Boom, a former romantic interest of Rictor, seems much more at ease with Rictor and Shatterstar's relationship then Wolfsbane.
- Darwin tells Professor X he was looking for after his "death". This is actually how he came into contact with X-Factor.
