Stoic and composed felon, Gus Fring (4-9)
I believe the answer is:
long-suffering
'stoic' is the definition.
(thesaurus)
'composed felon gus fring' is the wordplay.
'composed' indicates an anagram.
'felon'+'gus'+'fring'='felongusfring'
'felongusfring' is an anagram of 'LONG-SUFFERING'.
'and' is the link.
(Other definitions for long-suffering that I've seen before include "Patient in adversity" , "Extremely patient" , "Stoic, patient" , "Enduring without complaint" , "Stoical" .)
