"So, it is like that," Billy said. "You two are pregnant, and our family will grow even further, but even thought I want to spend every bit of these precious moments with you, Alexander and Lily will need you. Besides, some spies might be around, so they will notice if all of us disappear."
Kate and Natalie were silent, they were happy about the news, but then the last few events seemed like someone threw a bucket of cold water on them. It was really annoying, but they couldn't contest Billy's reasoning. It was too risky to go with him since they didn't know for how long the mission will last.
"Besides, I want to avoid sex during your pregnancy as much as possible and I feel like I won't resist if I stay here doing nothing," Billy said.
"Of all things you could have said now…" Kate said and then sighed.
"Do you think that this will take too long?" Natalie asked.
