The Lady of Summer's powers must only work on organic life, because the only rose not banished was a cloth iron-on patch on the Lady's hat!
The Snow Palace's password was 'snowflake.'
Gerda: Wherre is he (Kay)?
Lady of Summer: (gets answer from her hat) He's in the frozen north with my sister, the Snow Queen. Close to freezing himself, I fear.
Gerda: Why would the Snow Queen want to hurt Kay?
Lady of Summer: No sister of mine would ever harm a hair on the head of an innocent boy. That goblin's at the bottom of this.
Gerda: Is it always summer here?
Lady of Summer: Always. 'Cept when I find frost on my gladiolas; then I know my sister- Old Icicle Eyes- The Snow Queen, has passed through.
Mr. PineTree: Oh, sorry. the little fella just got away from me.
Gerda: Are you talking to me, Mr. Pine Tree?
Mr. PineTree: Of course. You don't see anyone else here with a lump on their noggin.
Kay: Is everthing in here frozen?
Snow Queen: Always. Except when my sister visits. She's the Lady of Summer and she likes to melt my palace gates for what she calls...."laughs."
Goblin: This is where the trouble starts. Fall and sting those human hearts!
