Sulu had firsthand experience with some terrible viruses; he knew Jack was right, and that the things the community might do to you could be far worse than a gender-swap or a stubborn shirt. He'd been bitten by a zombie, for God's sake - he'd felt just what that was like, and sometimes he would relive it in his sleep. He'd seen his captain deal with the death and destruction of his entire crew and had been unable to reassure him that it was all fake.

He frowned and looked away, grabbing a lock of his now long hair in his free hand, the hand locked with Ianto's brushing against the man's hand before he thought better of it. Jack probably wouldn't be offended, but there was no way to distract the conversation away from it. "Yeah," he said slowly. "I know all about that. But," he said after a moment, looking back at Jack, "I didn't stay that way and in the end, I know it was a one time deal, that it was temporary. All of this is temporary." Hopefully he wasn't referring to this thing with Ianto, which seemed to be blooming under the community's "gentle" care.
