Sitka changed Kenai back into a human and Denahi has finally realized that he was chasing his brother this whole time, and he is shocked by what he almost did. When Kenai sees Koda and tells his brothers that "he needs me", Denahi states that Kenai looked better as a bear anyways.
77"No matter what you choose, you'll always be my little brother." Who said these words?
Answer: Denahi
Denahi was about to kill Kenai when Sitka turned him back into a man. Denahi was suprised and awed; he threw down the spear he was holding. Kenai decided that he wanted to remain a bear. It was Denahi who said "No matter what you choose, you'll always be my little brother." He was speaking to Kenai.
78When Rutt and Tuke are playing a game of "I spy", what are they still talking about?
Answer: a tree
They are playing this game while they are traveling on mammoths. They mention that it's green, then tall, then something with bark and then a vertical log. And after this they are arguing if it counts or not.
Koda says this while he is the ice cave with Kenai. At this point, Kenai has not warmed to Koda, but by the end he sees him as his brother, and takes the form of a bear forever so he can look after him. How sweet!
