Kain's appearance is something of a relief, to be honest. At least he is familiar, unlike literally everything else. At the same time...there may be no one Golbez would rather see less.

"I am not here to provide it." Wherever this is, he does not feel the compulsion to fight with which he has become familiar. Nevertheless, he will defend himself if Kain renders it necessary. "What is this place? Where is he?" No need to elaborate; there is only one 'he' between them.
