I always thought cecilia was someone they both obviously care about and respect but is the friend you check up with every few weeks or because of the different path they choose for themselves and due to their different mind view and how they go about executing their goals and helping mutantkind.
I wouldn't mind seeing monet, storm, rachel, jubilee and betsy once she's done running around the otherworld reunited together again. And I need the theresa and monet reunion like yesterday.
