The person who got to TAC was Dr.
That is the problem I am having.
Ryu says he couldn't target TAC for something else.
I think I understand what you're struggling with.
Let me explain
Prof claimed to have gotten TAC's shadow, meaning he got added to his dead chat.
And he gets one random ability from that role.
He also has an x shot to amp the ability.
Mafia controlled/absorbed TAC's role to use his role abilities.
They aren't mutually exclusive.
