He remains silent through the whole affair, not protesting the movement but not helping much either. He can hear what Siebren is saying, but he doesn't really absorb it.

All he knows is that he is in pain and hunted, but Siebren is safe enough - he's from the train. Unless he's still under the illusion - but his thinking is slow and by the time he's formulated any idea, he's been put on a couch.

'Can you respond' is a difficult question to answer. He lifts his head despite it feeling like a thousand pounds and blinks slowly at Siebren. He tilts it slightly in a 'maybe' sort of gesture.

It depends on what's asked, and he winces at the emptiness he felt trying to claw back at him.
