Go to the next area. You'll only catch him in the last.
Regarding minotaur to get the scenes, I highly recommend getting all the hypnosis tiers before finally getting captured. (also don't bother trying to survive the capture after penetration, you trigger the last hypnosis scene after losing.) To make this easier, get all but the last tier, die/escape, refill hp, then reenter the fight. The endless looping appears to happen if it tries to trigger hypnosis when you already have all hypnosis tiers.
Regarding the dragon (which I note is mis-spelled as tracon), I also highly suggest getting all the hypnosis tiers before going for the scenes as there appears to be a looping issue if you try to exit the scenes after the 1st stage without fully completing the scene.
