I've talked about this book's "acknowledgment" of Krakoa and such already. How it's written in such a way where you need to be a long-time hardcore X-Men fan to catch those things, and if you're not then it looks like quirky text that Leah just made up. The closest she's come so far to acknowledging Lorna's history was Lorna and Siryn talking about what Siryn had to do to help Lorna back in X-Factor #244; which notably
DIDN'T acknowledge Lorna's origin story being told. It didn't say "Siryn had to do that to help Lorna deal with learning she killed her parents in a plane crash when her powers awoke as a kid." It just said, quote, "I once came so close to cracking this world apart like an egg that you had to make a deal to host an ancient death goddess just to save my 'fractured' mind..." Just enough to establish Lorna and Siryn have a history, which Siryn needs for a story arc focused on her. Not enough to learn something meaningful about Lorna herself.
But, in fairness, the scene does for once acknowledge Lorna has some history. In that it acknowledges Lorna's existed as far back as 2012. It's better than past issues in that regard.
No, the book acknowledging Lorna's history with Krakoa doesn't require citing a specific issue. But true acknowledgment would've been something along the lines like "Hey, remember when Storm, Cyclops, and Havok helped me throw you into space?"
That provides readers a clear sense of "Huh, so she's been around a while and has history with familiar names." As opposed to what X-Factor #1 did where you could just as easily imagine she's Krakoa's ex-girlfriend and they had a bad break-up.
