[[WMG: The girl Marti met at the record store is her half-sister.]]

Not just because she's played by Aly Michalka's real life sister AJ but because she had a definite reaction when Marti said who she was looking for. Also why did "Pops" profess not to know who she was talking about if he's such an authority? He at least knows the relationship or maybe even ''is'' their father.
* Confirmed although "Pops" is not the dad.
[[WMG: The channel to pick up from where the 1st season ended will be Creator/ABCFamily.]]

Think about it: Creator/TheCW decided not to renew it. Series/SeventhHeaven aired previously on both ABC Family (in Reruns) and in The WB (its original channel). There's even a tweet that hopes that channel will pick it up. And with two Disney graduates in the show (Three if you count Series/PowerRangersDinoThunder's Emma Lahana), there's a big chance it'll continue there.
