Riku was STILL going to give the Prince sad eyes, unset that Sora was going to be unhappy, and there was nothing he could do to help or prevent it. "It is my job to worry about you," he insisted. "As it is to support you, and protect you, and care for you." In his role of Beloved, he had no greater task.
"You say you will be alright," Riku moved a little bit, rearranging himself so that he could hold the Prince in his arms and lean back against the stall wall, "But I do not like it still." He looked up at the horse. "See, Orion agrees with me."
But, right now, winter was still in the future, and Riku kissed the Prince's cheek and signed. "But I will try not to worry on it NOW. You are relaxing today, as am I." And the point was to NOT worry.
