Tadhg gives the train only a cursory glance as it shifts, and instead stays focused on the man moving it. What happens to the huge metal construction is self-evident, but the way Lehnsherr's patterns twist and stretch to accommodate the forces he brings into play fascinates him. His hands continue working without much in the way of conscious direction from him, shutting the truck door behind him, arranging his sword at his right side, drawing one knife to hold poised in his fingers.

When the man in kevlar falls to all fours, he steps forward, starting to extend the hand not occupied with the knife to offer his healing powers, but he hesitates. Lehnsherr shows no signs of injury, and Tadhg is not at all sure how his fairy energies would interact with this whatever-the-man-does in any capacity other than healing. Instead he converts the gesture to an offered hand up, should it be needed, though he's not at all sure how Erik will react to that, either.

"Well done." He keeps ears, eyes, nose and more arcane senses spread wide, hunting for any potential threat within the cars that might have been wakened by the movement, or any without that may have heard the noise. The knife glints in the fog-diffused light as he steps between Erik and the train.
