You and your roommate were having fun when they get the news that a bomb was about to drop, both you and her ran like hell to the vault just in time before the bomb dropped, you two put on your vault suits and get in the cryo chamber, after a friendly hug, the ice closes, 200 years later, she managed to break out, she looks at you with a sad expression, she says something, but it was mumbled from outside the cryo pod, she walks away, 4 years later, she comes back in T-45 power armor and opens the pod, you fall out but she ends up catching you

"Easy there, I told you I'd come back!"
