Many of the X-Men have been acting odd or even somewhat out of character since the mutant nation of Krakoa formed and their leader, Cyclops, is no exception. Although Scott Summers is still the dedicated soldier and general that he's always been, and arguably has grown even more confident and inspiring by standing up to the corrupt Quiet Council, his personal relationships, especially with his family, have changed in unusual and unexpected ways.
His relationship with Jean Grey and Wolverine, which has seemingly evolved from a love triangle into a polyamorous romance with both of them (that may also somehow include Emma Frost) has sparked a lot of discussions but his relationships with the rest of his family, especially his time-displaced children, have also changed pretty drastically.
Since "Dawn of X" started, the convoluted Summers family has effectively been living in harmony with one another for the first time. Scott's formerly strained relationships with his kids, Rachel/Prestige and Nathan/Kid Cable have shifted to more simplistic, and apparently happy, dynamics. They all live together with Jean and other relatives like Havok (and weirdly enough, Wolverine) on the moon and Scott often brings Cable and Rachel along on missions, which they comically treat as family outings. At first glance, it might seem nice that Scott's notoriously messy home life has seemingly stabilized, but when one looks closer it's hard to deny that his new dynamic with the kids is rather strange, even unsettling.
The strangest thing about Scott's relationships with his kids is how he, and to some extent Jean, infantilize them. The fact that they live together isn't really strange considering the mutants' unique situation, even though both the "kids" are actually adults (or at least young adults in Cable's case) but the way they act around one another and refer to each other definitely is. Scott refers to them as kids, both to their faces and when discussing them with others and in many of their interactions Rachel and Cable, particularly the latter, come across as childish, such as when Cable whined about wanting a new weapon only to be reminded by Jean about household chores. Rachel at least has some independence due to her membership on X-Factor but Scott and Jean also frequently come across as overbearing, accompanying her and Cable on superhero missions, which diminishes and ignores their individual capabilities. Rachel has been an X-woman for years, Cable is a trained soldier, and both of them grew up in nightmarish futures where they constantly had to fight to survive -- they don't need their hands held.
The dynamics between the characters also largely ignore the complicated, often unpleasant history they share. All members of the Summers family have made serious mistakes in their relationships with one another but the newfound harmony between them seemingly ignores this. Scott, for example, hasn't always been a great father, with his most famous failure being when he abandoned young Nathan and his mother, Madelyne Prior, when he discovered Jean was alive following "The Dark Phoenix Saga". Rachel spent a long time in the present before even telling Scott and Jean they are her parents after being disturbed at learning about Nathan, who did not exist in her timeline.
Most recently, Kid Cable marked his arrival in the present by killing the original Cable, with who Scott had a much longer and more complex relationship. The X-Men allying with former enemies is a defining element of the "Dawn of X" era but Scott becoming so close to the man who killed his son, even though he is also his son, is especially hard to take.
Scott's new relationship with Jean and Logan, while somewhat surprising, also feels like a natural evolution for the characters and is an important representation of a non-traditional romance by mainstream comics icons. But his relationship with his children is bizarre, sometimes even creepy, and is one of many pieces of evidence that indicates that the Krakoan mutants aren't all in their right minds.
