Why did Rome look familiar?

Yesterday, Rome, Rei and Aason were finally allowed to move back into their house which had to be rebuilt after the would-be assassins, Troutman and Steele, had blown it up with a bomb. Since they didn't really have a lot of belongings, it didn't take them the whole day to move back in:

     Mother, father and son had finished their evening meal. After a rousing game of hide and seek, Aason declared himself ready for bed. Rome was happy to oblige. It wasn’t long until he was tucked in and fast asleep in his very own bed. It had been a long time for the brave little boy. Rome stood in the doorway and watched her little angel breathe in and out, in and out. Eventually, she sighed a happy sigh and closed the door.
     She took one more stroll around their newly rebuilt house then joined Rei in the bedroom which smelled of fresh aerogel. Rei was lying on the bed, without a shirt, reveling in not having to wear the vest any more although it had proved to be invaluable not just in saving his back but in saving his life.
     Rome changed into her loose-fitting pajamas and joined her husband on the bed, marveling at the peace and serenity a little thing like being home brought. She snuggled up to Rei and delighted in the fact that she could stroke his chest hairs knowing he was fully healed.
     Rei put his arms around her and found the sensations excited him. Rome smiled and said, “There will be plenty of time for that. There is something I need to share with you.”
     Rei cleared his throat. “I’m not a hundred per cent sure I want you always reading my mind,” he said. “There are some things I’d probably want to keep to myself.”
     “I will respect your privacy,” Rome said, scooting up the bed a little. “But there will be times you will not regret it.” She smiled broadly but there was a hint of naughty in her expression.
     “Oh, yeah,” Rei said. “In this case, I think you’re right. But I believe I owe you a session like you gave me during your training.”
     “I would like that,” Rome answered, “but I promised you I would tell you the information the Overmind of Earth imparted to me just before we left the planet.”
     “What?” Rei asked, not knowing whether to be dismayed or intrigued.
     “Do you recall the first time you saw my face back on Dara? I was on the other side of the bulkhead. You once told me I looked familiar to you even though you had never seen me before.”
     “Yeah,” Rei answered. “I figured it was because I might have seen your face in your spacesuit helmet when you revived me.”
     “No,” Rome said mysteriously. “That is not why.”
     “Then why?”

Tomorrow, we will find out.
