Walked quietly with faction to safe environment (6,4)
I believe the answer is:
padded cell
'faction to safe environment' is the definition.
I can't tell whether this definition defines the answer.
'walked quietly' is the wordplay.
'walked' becomes 'padded' (padding is a kind of walking).
'quietly' becomes 'cell' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'padded'+'cell'='PADDED CELL'
'with' acts as a link.
Can you help me to learn more?
(Other definitions for padded cell that I've seen before include "secure accommodation" , "psychiatric unit facility" , "Secure site" .)
