Quote 7
Lucy felt very frightened, but she felt inquisitive and excited as well. She looked back over her shoulder and there, between the dark tree-trunks, she could still see the open doorway of the wardrobe and even catch a glimpse of the empty room from which she had set out. (She had, of course, left the door open, for she knew that it is a very silly thing to shut oneself into a wardrobe.) It seemed to be still daylight there. "I can always get back if anything goes wrong," thought Lucy. (1.25)
Lucy balances her desire to see what's out there with her instinct to remain safe by keeping the wardrobe door open – literally maintaining the connection between the unfamiliar and the familiar.

"We can pretend we are Arctic explorers," said Lucy.
"This is going to be exciting enough without any pretending," said Peter, as he began leading the way forward into the forest. (6.21-23)
Lucy, the youngest, is still ready to treat Narnia as a child's adventure game, but Peter has realized that they are starting off on a much more important quest.
