Kyle was only allowed an hour to be with his kids, and he spent the entire hour just talking to them. It may have been his imagination, but it looked like they were listening. Their heads were turned towards him, as if they knew that he was their father.
When it was time for him to go, he touched the incubator and promised them that he'll be back when he was allowed to.
After he left, the twins appeared slightly agitated, as their tiny feet kicked out and hands moved a bit. They only settled down when their hands touched and their heads naturally turned towards each other.
When he got back to his room, he looked at everyone and announced, "I'm registering my marriage to Sayuri now."
No one objected.
The Smith power and Sam's efficiency was truly a scary thing. The forms were filled in, signed (in Sayuri's case, thumbprint) and validated within a few hours. Once done, he kissed her on the lips.
