Heidi wasn't the kind of person who believed in fate until this miraculous discovery. "I didn't believe in fate before finding that out, but there's no arguing with it - we're clearly meant to be together," said Heidi.
Heidi has changed her mind about her beliefs, as it is evident that everything happens for a reason. Meeting Ed once again couldn't have been a coincidence. Fate brought them together and this discovery cleared every doubt that Kay had about her future son-in-law. The hunch she had was only a sign that Ed was the perfect man for her daughter.
