Wait....

So that would mean....

Heinz was married to Delia at some point, and the two had Ash. Heinz left Delia... Heinz married Charlene, and the two had Vanessa.

But Vanessa is older than Ash...

So that would mean either 1 of two things:

Heinz cheated on Charlene and smashed Delia, or...

Ash is truly forever 10.
