Spencer had never known he could feel so many emotions in such a short time.

Aaron was back. Spencer was happy.

Aaron had lost weight. Spencer was worried.

Aaron had grown a beard. Spencer was turned on.

Aaron started talking about some decision he had made. Spencer was nervous.

Aaron told them he had lied about Prentiss' death. Spencer was confused, shocked, hurt, angry. Glad that she was alive, but pissed that Aaron had not told him.
