As Starscream speaks, there is a distant sound of engines, growing steadily and rapidly louder. By the time it's close enough to really notice, though, it's too late – mere seconds later there is the sound of transformation, and the stone shakes with the impact of several tonnes of metal. The entrance to the cave is blocked by a huge shadow as Megatron straightens up.

For a moment – too long a moment – there is silence, as he surveys the three Decepticons with a critical crimson gaze, optics very slightly narrowed as he takes in what, exactly, he has been given to work with on this planet. It doesn't look like he was much expecting to be impressed in the first place, though. In fact, he looks furious, and as if he's been furious, probably, for hours; as if this is just one more aggravation, one more disappointment, to be added to a very, very long list.

But all he says is, "It seems I have interrupted something. Please, Starscream, continue – what is it you have lost?"
