To be fair, Regina controlled Storybrooke so she could probbaly stop the results of a blood test one way or another. In HH, there's nothing stopping Henry and Jacinda except their own "mental gymnastics". Like all Weaver has to do is tell Rogers and Tilly that they're father-daughter, and then make them take a blood test to prove it. No one would be able to stop it from happening.
