Paul, it's me. Tina. I heard back from my sister Candace. We couldn't get into a Vault. 101, 87, didn't matter -- all full to capacity. But my brother Alex is a soldier and... he sort of stole the pass code for a secure Army bunker. He did it for the family. But they caught him. Before they took him into custody, Alex he sent each of us one number of the four-digit code. That way, we all have to be together to get in. He gave me number "5" -- the day of my birth. So I guess what I'm saying is... I'm still leaving. It's been fun. Kind of. Oh, and I'm not pregnant! So no worries.”— Tina, on her holotape
