It may not be. I remember that when Spectre failed to assert his Thrall, I could sense Vita, and he says that it was vice versa. So the flickering could indicate some comatose state. I am not sure how likely such a state is for him, however.

How likely is it that the flickering indicates a comatose state irrespective of his likelihood of being in said state?
