Lelouch was surprised by the hug, but didn't pull away, and neither did he hug back. He simply stood there and couldn't fathom why Patchouli, who he met just a few days ago, would want to give him such a sencere sign of worry and comfort. Lelouch had a hunch that his father was responsible for his mother's death - but he didn't know who exactly had killed her. He wasn't about to let Patchouli know this, however. He hated his father enough to want to kill him over and over again but he had no reason to drag Patchouli into his hatred as well - unless she wanted to be dragged in, of course, then he had no objections. And suddenly, all of his bitterness went away, being reminded of Patchouli's presence, and it was replaced by a certain sadness along with happiness because this time he had a true ally - he had a friend.
