Wonder if they'll move. She seemed super excited to tell her sister so I assume they must be pretty close. I could see them splitting up at some point as I can see Kara wanting to settle down in one place but Nate wanting to carry on with their current lifestyle. I just got the impression he wished it had taken longer to happen as he kept saying how people said it would take longer as they were olderSaid a lot, that one of his first questions was 'wait, can you still come to Antarctica with me in November for my ultra marathon?'
I know they fell in love with Colorado when visiting Rick and Bec, but it will be pretty isolating for Kara there all alone with her parents in Tennessee and her sister in Texas once the baby is born. That's a long travel just to see family.
