Pretty interesting choice for a story arc involving refugee / former child soldiers. But it was obvious right from the start that the 'Big Bad' was the janitor that let Booth and Sweets into the victims room. No surprise there. But the best part about this one wasn't the main story, but Cam and Arastoo announcing to everyone at work that they are in fact a couple. That's the best part? No. The best part was Hodgins mockingly clapping in approval. Haha. Funny.
