In my opinion he should be present in the first fight when Darak runs away, the sewers is more of a secret “solo mission”.
Talking about the fight when Darak runs away I find it strange that the heals and secondary enemies die so quickly, it ruins the atmosphere a bit, in my opinion they should have a lot of health and do very little damage and poise damage, so they are useless but still make a scene, and the same should be for Randolph.
The thing that bothers me the most is that they leave him with his armor which also has some scabbards with daggers still in it
