Light and Misa were captivated, and after 50 days, when they were released, L declared that all the task force members work in the private HQ, and live there. L was still suspicious of Misa and Light, and to keep them under surveillance, attached cameras in their rooms, and also, handcuffed himself to Light so that they could be together 24/7. Light wasn't in favor of the idea, but since he had no memories of him being Kira, he had no problem because he was convinced that he's innocent.
