Sulu wanted to be angry, to be pissed off at Ianto for hiding this from him, for risking his life so soon after being brought back and for keeping it from Sulu. He wanted to be mad so he wouldn't feel terrified all over again; he wasn't used to the feeling and he didn't want to get used to it. Anger was a good, solid emotion that wasn't weak and horrifying. But he couldn't - he couldn't stay angry. He couldn't stay upset when Ianto was starting to panic himself, when Sulu could hear him starting to lose it.

"I know you don't," he said quietly. An apology for getting mad at all was almost out of his mouth but he held it back, because for once it really, honestly wasn't in him to give an apology for how he was feeling. What he was feeling was natural and honestly expected. "I know you don't want to go back, nobody wants you to go back." He pushed himself out of his position, shuffling forward on his knees until he could lean in and wrap his arms around Ianto. "I don't want you to leave again and I will do anything to keep that from happening. I promise." He just didn't know how, quite yet.
