Sulu had to struggle not to grab Ianto as he pulled away, forcing himself to focus all his attention on not panicking. He was going to be fine - he'd be more fine if he wasn't having such an intense allergic reaction and even more fine if he could just plain breathe but it would be okay. He tried to calm down despite the fact that pulling in air was nigh on impossible and gasped, feeling like a fish out of water in all the literal, terrible ways.

He tried to shout to Ianto that it was the hypospray in the inside pocket but there was no way he could get out a word, much less one as hard as "hypospray" - he could only hope Ianto would realize what it was when he saw it. Instead, he looked up to the cloudless sky and tried to focus on that for a while, despite the gray seeping in all around.
