In one of the earlier cutscenes where Geralt, the duchess and Damien have an argument about Geralt not managing to kill the beast, Geralt mentions that it takes another one of its kind to kill a higher vampire. Later on after we get rid of Detlaff nobody questions whether there's another vampire they don't know about who helped Geralt, or whether Detlaff is going to regenerate at some point and become a threat again.

Do you think it's an oversight by CDP or am I missing something?
