What might suggest hero a moderate? (6-2-3-4)
I believe the answer is:
middle-of-the-road
'a moderate?' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for middle-of-the-road that I've seen before include "Unexciting" , "Average" , "place for dangerous drivers?" , "Avoiding extremes; moderate" , "Safe" .)
