Consented to get a vice (6)
I believe the answer is:
agreed
'consented' is the definition.
(agreeing is a kind of consenting)
'get a vice' is the wordplay.
'get' says to put letters next to each other.
'vice' becomes 'greed' (I've seen this before).
'a' put next to 'greed' is 'AGREED'.
'to' is the link.
(Other definitions for agreed that I've seen before include "Corresponded" , "Harmonised" , "Expressed willingness" , "I'll go along with that" , "Jointly decided" .)
