Conversation so far:
What happened in Resurrection?
For a time, Kitty Pryde and Nightcrawler express some resentment over the X-Men's failing to contact them after their supposed deaths.
Did they ever contact them?
Following the wedding of Captain Britain and Meggan, Excalibur disbands and Nightcrawler returns to the X-Men with Shadowcat and Colossus.

Question: What else happened that was important?
Self-contained rewrite: Along with Nightcrawler returning to the X-Men, what else happened that was important?
