There's some things that happened on Telos that would sound daft to most people, although maybe not as much to those from the ship. However, he figures it wouldn't hurt any to explain at least a little bit about how they were there.

"Aye, well, there wasn't any real duty to speak of. The Doctor, Victoria and I were traveling together, and we wound up in the same place as the expedition, that's all. We did agree to lend them a hand, but it wasn't something we had been planning on doing."

It never was, really, he thinks, but he doesn't get a chance to dwell on that thought for long. When Cassie freezes, all thoughts of his past travels slip away, lost to the present moment. He doesn't care for the idea of her being the one to search the bush, but he's not fast enough to stop her. With a small frown on his face, he stays back and watches instead. If there is something there, two of them trying to sneak up on it could very well scare whatever it is away. That doesn't mean that he won't be prepared to rush in if need be, and one hand drops to his waist, where he usually keeps his dirk sheathed.

Fortunately, it turns out that it's an unnecessary gesture, and after it's clear there's nothing there he walks up to join her, bending down to try and peer at the roots of the bush to see if he can see anything. He can't, but he's beginning to wonder if there is something there after all. It's not as though it could have been the wind, however - the air here is as unmoving as some of the rocks. So what could it be?

"Whatever it is, it's a very canny beastie. Maybe it's an invisible one, too."
