Ianto shut his eyes, smiling softly as he cradled the phone to his ear. "Likewise, Lieutenant Sulu," Ianto said lightly. "I look forward to your call, and well..." He paused. "Sleep well, alright? ...Goodnight." Much like he didn't want to make the last move of the night, Ianto didn't want to be the first one to hang up, either. He waited, listening for either Sulu to say one more thing, or for the click of the call disconnecting.
