It's as if the twins had noticed the mood of their father and therefore they tended to believe him, as throughout the whole journey they were equally excited and they were equally clapping, their hands explaining the same mood as their father.
"Yes, That's it, my babies. That's it! You're gonna see Mama today. She has a woken up. You're gonna get new names today. How wonderful. How beautiful!"
All this while, Liam had adjusted his voice so as to fit into the character of a child, making it sound so baby like despite his age.
The twins continued giggling as they clapped up and about, clearly as excited as their father because they could sense that whatever he was telling them was so beautiful and was something that was so amazing.
Jane on the other hand tried to look at herself from head to toe as much as she could reach because she wanted to look extremely presentable before her own children.
