Notes from Skype:
They got married about 3 years ago (we can figure out their anniversary later). Then Zach found out his mom had another kid and figured since they got married they needed another baby too and started talking about wanting a little brother or sister. They both initially said no way, but slowly warmed up to it. Now they're moving to New York to be closer to both of their families when the baby comes and they're getting ready to go through the medical stuff to make a baby.
