Belkar's Character Development?

[Fyraltari]

Oh yeah, such good friends these two.

Belkar Knows that That Isn't Durkon. He was friends with Durkon, and he knows / senses that the vamp isn't Durkon. He saw the whole conversion process.

On a more humorous note, more evidence that he knows it isn't Durkon ... last panel.

I meant panels 2 and 3.
