Concentrating hard on the tricorder and the readings, Rangin doesn't hear Graham's approach until he hears the voice close to his left ear. Instinct takes over and the next thing he knows, he turns the tricorder on edge and swings it hard back at the source of the voice right behind him, stopping only at the last moment as he recognises the ugly tone as being from Ens. Graham behind him. Wondering if he should have swung harder and kept going, Rangin slowly lowers the tricorder mere inches away from Graham's face before realising that Graham is not in any danger from him. He had already started to move back and out of the way with one hand coming up.
"I hope you have a good explanation for sneaking up on me like that yourself, given I'm trying to follow this trail and make sure I don't miss anything, like anything Kylah's assailants may have left behind, or do you only care more about annoying your shipmates in stupid ways."
Rangin steps back and drops the tricorder to one side and crosses his arms looking furiously back at him. "Why was I on board?" before freeing one arm and gesticulating at him. "Don't be an idiot Graham, shore leave had ended, why wouldn't I be on board?" The tone in his voice saying making clear what Rangin thinks of Graham's question.
"If you'll excuse me, I have a job to do and you're getting on my nerves." Rangin continues, his voice dripping with ire, "You want to help, stand there, shut up and stay out of my way. I'd rather you didn't trample all over the trail." before turning his back on Graham and getting his tricorder ready. "You know, you could try thinking, once in a while." Rangin dramatically taps the side of his head before going back to scanning muttering something indistinct and vulgar under his breath about the last thing Rangin wanting is Graham getting in the way while he tries to find out what happened
