On last night's episode of The Simpsons (the first new one in over a month), Lisa met a like-minded girl named Juliet (Emily Blunt) at an after-school program and the two became fast friends.

However, their friendship followed the plot of Heavenly Creatures in which the two girls get trapped in a fantasy world of their own creation and alienate themselves from reality until their families decide that they shouldn't be spending so much time together. Lisa, who is always a little more mature than her parents, realized that Juliet was kind of a nutbag on her own, and let her friend go. Clip above.
