GR translation: eyes riveted on blue Thanatz

[Mike Jing]

V671.17-24, P684.23-30   One day they come for him: he is lifted from the
straw as black with coal-dust as they—lifted easy as an infant, a roach
flicked in kindness off of his face—and transported shivering, gathered
moaning south to the Erdschweinhöhle where now they are all sitting around
a fire, smoking and munching, eyes riveted on blue Thanatz, who has been
gabbing for seven hours nonstop. He is the only one privileged, in a way,
to tell this much of the story, he’s the fella who lost out, the loser,

The word "blue" here refers to his emotional state, is that correct?
