Uncanny X-Men #269 is Rogue's only appearance in a comic in 1990. When we last saw her, in #247, she was fighting Bastion, sacrificing herself to save everyone.
Cut to: Rogue waking up in that town in the Australian outback that the X-Men briefly hid in, and learning about the assassination of Mystique and the death of Destiny from the tellybox. I'm surprised at Rogue's naivity here: news involving Mystique should not be interpreted at face value, and although we as readers didn't see anything that contradicts the report, surely that's Mystique pretending to be Val Cooper...
This is another puzzling issue, featuring a fight with the original Ms. Marvel who seems to be being controlled by the Shadow King, guest appearance of the Muir Island X-Men, who appear to have gone bad, and, of all things, a cutaway to Lila Cheney, of the Shi'ar Imperium. And finally Magneto arrives in time to save Rogue... (What's he been up to, anyway?)
It also contains a good candidate for the X-Men's worst racefail yet. Rogue has occasion to nick powers off Gateway (discussed previously). As she does so, her skin colour changes. (No other aspect of her appearance, mind.) The? Please let this just have been a miscommunication with the colourist.
