However, Mike's relationship with them as a grownup is complete fantasy. Mike didn't have a passive temperament, and Mike was angry. For some reason, I have a feeling he'd see things more clearly than his sister as they got older. I can pretty much guarantee that in his 30s his parents would be lucky if they got the occasional Christmas card from him.

It would make more sense if he were more like Aaron at that; that's why in the little fixfic on the Foobiverse, he's pretty much spat out all the Kool-Aid.
