Oh her father is in real estate! Which is perfect considering she had to go through the whole storefront buying business and probably knew nothing about it. I'd love a close friendship, as well. Possibly, if her father was down for it, he could have been an investor in her business? (or silent partner or something?) At the very least, she would have relied on him for the space buying. Maybe they met at a part that Cammie was throwing/hosting something that would have had them in touch to work with her ex-boss? (the pastry chef she eventually won the show with?) and their friendship blossomed from there?
