Ianto shot Sulu a look at the suggestion that he was afraid of a tiny woodland creature such as that one. He wasn't afraid of the creature itself, after all. It was the unknown rustling of bushes in an unknown area of an unknown planet that gave him pause. He was considering stepping forward to see if the deer-like creature would let him pet or touch it, if it would be skittish around humans or not. Of course, that was around the time that the creature came out of the trees behind it and devoured it in one fell swoop.

Just as Sulu was reaching for Ianto's hand at that moment, Ianto was throwing his out to grab Sulu's, his heart in his throat, because that thing was a lot bigger and more terrifying than he was really prepared to handle in that moment. He simply threw his hand out to grab Sulu's, and without a second thought was tugging him as fast as he could in the opposite direction. Maybe running was a bad idea, but Ianto sure as hell was not going to just stay put and watch as it came after the pair of them as well.
