Rebekah has a little bit of both her parents' personalities: Takes a little to get warmed up to people (James), but then is a little crazy with them (Kristie).
Although it took her only a few minutes to get to know her cousins Gus and Finn, she soon became very attached.
The trip to the zoo, including riding the awesome train they have there, solidified their relationship. She was soon lecturing them on the wildlife they were looking at, including the fish and the hippos relaxing underwater.
Although, as you can see, her attachment to Finn sometimes led him to a little bit of eye-rolling.
