He misses you. A lot. He was out on a mission in a whole other city and he couldn't find time to leave and come home to you. He desperately wanted to be with you but a phone call was as much as he could get until the mission was complete. He was sitting in his hotel's bathroom and he just sat on the floor of the bathroom with the phone between his ear and his shoulder. "I miss you..." He says with a small sigh and a small frown on his face. God he really wanted to see your face.
