Not easily, but they take it well.

You knock on Sabrina and Rowan's door and Sabrina opens the door.

"I just had a call from the specialist and he had some big news" you say entering the room. "And" says Rowan. "Well your baby is a healthy baby girl with the DNA of all three of us" you say. "What!!!" Says Sabrina. "The doctor also said that you should give birth in about 2-4 weeks time" you add. "Something about the process being abnormal. Have you thought of a name?" you ask.

"Yes, Maya" said Rowan and Sabrina simultaneously. "Ok then" you say.
