katladyd, well, actually, I'm always feeling a little sorry for Luna in moments like that. She can't do anything without Lily interfering, and it stresses her a lot. She's the older one, but she can not compete with Lily, and Lily scares her. Sometimes Lily would just stare her down, but at other occassions she's jumping onto Luna's back, and after that, she's chasing her across the entire apartment. Luna doesn't know how to deal with that, she's just hissing and growling for her own defense, but that doesn't impress Lily at all.
