Numbly handing the CiD to Jack, he waited for Jack to go through all the same step he had, not saying a thing. There was some vain hope Ianto had missed something, but then Jack scanned the device with his wristband, and Ianto knew very well there was nothing wrong with the device itself.

"Maybe... Maybe she had to hide for some reason? If anyone could make it look like she just disappeared, it's Tosh..." But his voice weakened and trailed off at the end, and it was clear from the desolate look on his face that he knew he was just clinging to false hopes. If Tosh had needed to disappear suddenly, she would have found a way to let them know. Tosh was gone, and Ianto's spinning thoughts were none too different from Jack.

What would he do if Jack disappeared and Ianto were left here without him? What would he do if he were forced to leave Jack behind in Baedal, never to see him again, never to find a way to rescue him? As it was, they now had reason to mourn Tosh for a second time, and coming on the heels of this morning's events, Ianto felt rats in his stomach like he hadn't since--

Swallowing his fear and sorrow, Ianto was glad to be pressed to Jack's side. He rested a supportive hand on his knee, determined against all odds never to leave this man until death took him.
