I'm here NOW, but about to go to sleep.

It sounds fine, so long as you can have a valid reason for a younger girl to be in the CDC center. Maybe "future breeding stock?" Haha. 

But I'm ok with that. It's nagging at the part of me that screams "but the probability of them surviving and being united blah blah" but I am willing to work with you. 

Let me know here or via PM if you have any questions.
