Good chapter, there, and I loved how Harry managed to answer Molly's questions without annoying her; I suspect she'll start working with Ginny to redirect her at some other wizard (Look out, Neville!).  It's good to see matters progessing fairly smoothly between Hermione and Harry; that should make for some interesting times later on.  That new wand and Harry's other abilities are going to alter the correlation of forces more than I suspect anyone realizes (have to wonder how Dumbledore will react to the changes in Harry and his relationships).  I'll definitely looking forward to future chapters.
