The way we were:
After the switch happened months ago. Everyone comes together and looks back at the memories they had been through together. But now that Bay now has a daughter of her own who was switched at birth as well. They all tell her stories of how her mother was going through the same thing many years ago. With flashbacks that they remember. But then that’s when Regina has a flashback of the time when Bay was born and hires a private investigator to find her daughter. But now there is something else that happened that day that no one else knows that the hospital didn’t keep records of. Which leads to Regina’s flashback of that moment. And at least now they could look back on the good and bad times together.
