Severus and Regulus
Audrey's bakery didn't exist by the time Severus met his end in the Dreams. He did know her in his classes, though, when she was a student. Hufflepuff. She seemed to always be staring at the Weasley twins, which irritated him. Severus didn't believe in making celebrity out of those boys simply because they were troublemakers. But that was beside the point.
Audrey had likely not even been conceived by the time Regulus met his end in the Dreams, too. So neither man would have been able to fully enjoy the bakery that the magical Audrey put together in the Wizarding World. Though, this one was as magical as the Real World got to Severus. There was just something in the air here. Perhaps it was because it was run by someone from the Dream World.
"And happily so." Severus responded. "David was born last night. Romana and I need the fuel."
