I noticed this as well. I'm still on the first disc because I'm watching one episode per day, and tomorrow I'll start the second disc. At any rate, on the first disc, Vicki's first day/night lasted for like the first 5 or 6 episodes. I picked up that the days were being stretched out because Carolyn kept referring to "You're leaving? You just got here last night!" etc. So she arrived, met Burke, met Maggie, went to Collinwood, heard the widows crying, met Sam Evans, met Roger and Elizabeth, and saw David on the stairs all during that first night and the next morning.
She certainly knew how to make the most of her time. lol.
