Second half to the conspiracy: JackJack33 is Jackson85's dad. Allow me to explain...
All kids get some random half of their parents' DNA. From Molly, Jackson got the letter M. Now JackJack has two jacks, but Jackson has one. This is because Jackson got half of JackJack's name and half of his DNA.
Jackson85
JackJack33
This can be proved furthermore by looking once more at Jackson and JackJack's numbers.
8 - 5 = 3, meaning Jackson has (indirectly) a 3 in his name.
JackJack has two 3's. Jackson only has one because he only got half of JackJack's DNA.
FURTHERMORE, we can look back at the 'son' in Jackson's name. Jack - son. Jack's son. Son of Jack.
Jackson85 is the son of JackJack33.
Sorry if this doesn't make total sense. It's 2:30am. My brain tried it's best.
