Scully at this point is a BIG question mark. He could retaliate because he has nothing to lose anymore, but then again realizing that Franklin Saint has literally WIPED OUT AN ENTIRE FAMILY TREE due to them wanting revenge on him, he may wonder would it even be worth it anymore and lost the fight completely.
I think Skully still has a big part to play or he’d would have been killed off in this episode with Khadijah.
The only part that makes sense is the revengeful killer hell bent on seeing Saint suffer. Him scurrying off to join a chapel or some shyt doesn’t work for his character. The writers already played that hand with Melody. You can’t play that card twice.
SOMEONE close to Frank has to die this season and i’m thinking Skully is going to be the one to make that happen
