It actually starts in X-Men #321, during the Legion Quest story and it continues in Cable #20. So this is what was happening.
After Jean and Nathan are disconnected from the machine, Scott and Jean share a sweet moment together (another instance to disrupt that annoying echo chamber that Jean is the supporting adoring girlfriend/wife and it's not reciprocal) and then with Charles.
And later they talk to Nathan.
I really love this family and I hope Jean gets to hug adult Nathan too. She's a loving woman and his mother. Why not? :)
