After chastising Lin Wu with a pillow, Little Knife sneaked up to Lin Wu while sitting on a chair and whispered, "Hey!"
"Yeah."
Little Knife said, "I feel quite sorry for Shana, she's your partner and should have been the one to get the exclusive Skill Book."
Lin Wu sighed and said, "If you all think that way, I'll feel really guilty." Lin Wu's original thinking was very simple; Little Knife was a brother suitable for bringing along on an adventure. Shana was a friend, a coworker; it didn't seem right to expose her to danger without knowing what the reward would be.
The problem was that the reward for the mission was quite good; coupled with Stone and Little Knife's opinions, Lin Wu felt rather sorry for Shana. After all, she had been his partner for a week. The only time they separated, something like this happened. Annoying - sometimes it's better to mind one's own business. Without a partner, he wouldn't have these troubles, right?
