Sulu didn't need to be told twice that they needed to run - he didn't even need to be pulled very much to get his legs moving. He didn't bother looking behind him, either; the low, thunderous growl rising up into a howl was enough for Sulu to know that they'd been spotted. It had crossed his mind that maybe running wasn't the exact right response to the beast now charging after them, but it had been pretty obvious that it had seen them and he didn't think it mattered at that point.

As they ran, Sulu gripped Ianto's hand, pulling and being pulled as they sprinted through the thick underbrush. This was bad - very bad - if only he could risk being distracted so that he could grab his communicator and call for help - but he didn't want to risk falling over. As it was, he was sure he'd trip before too long. "Keep going!" he shouted to Ianto, as though the other man needed any encouragement in that particular field.
