So how is it that Elfangor managed to not only live on Earth successfully in the early 1980's, but completely integrated into society. He 1) Got married to Loren, 2) Worked in a tech company 3) Expanding human computing technology 10-15 years through his friends "Bill" and "Steve" (who may have used that to acquire billions of dollars, hint hint). (The technological advancements were critical for the Z-space transmitter that allowed the Andalites to be warned about the Anati ambush and defeat the Yeerks on the main front) and 4) had a son that played a critical role in Earth's
scooby gang human resistance.
[Ax, on the other hand, was consistently unable to control his human morph and ended up sending Jake to a psychiatrist.]
How was all this possible?
Cinnabon was founded in 1985. Almost certainly the exact same time Elfangor left Earth.
Boom. No Cinnabons = successful professional Al Fangor.
If Crayak had founded Cinnabon in 1980
... we'd all be living with a Yeerk in our heads
