Vanessa and Casper examine the theme of "Progress" in chapter seven of Harry Potter and the Order of the Phoenix. This week we discuss whether owls are an obsolete technology, The Fountain of Magical Brethren, and the power of Mamma Mia. Our question this week is: is progress inevitable?

Next week we're reading chapter eight, The Hearing, through the theme of Partnership. Thanks this week to Aya Ahmed for our voicemail.
