Old Auntie did not dwell on the word "also," merely assuming it was one of Fujino's habitual turns of phrase.
As for suspicion...
Of course she was suspicious. She reasonably suspected that everyone in the organization was an undercover agent.
After all, even an old veteran like her was a traitor.
Could anyone else in the organization possibly be a good person?
If they were not traitors, then they were definitely undercover agents.
As for whether there were exceptions...
Question: BOSS had won third place in a contest for loyalty to the organization.
Then who were first and second place?
Other than those two fools, Gin and Vodka, there was probably no one else.
Even BOSS was probably not as loyal to the organization as those two were.
Still, regarding Fujino's decision to let a fish slip through the net this time...
Old Auntie was still somewhat puzzled. She frowned. "What if he discovers it?"
"Discovers it?"
Fujino stroked his chin. "Then I can only send this friend I have known for such a short time on his way..."
Vermouth was a little surprised. "You would even kill an undercover agent?"
"Are undercover agents clean?"
Fujino shook his head slightly. "Putting aside what undercover agents are trying to do by infiltrating your organization, which undercover agent is clean?"
"Even without mentioning that, anyone who poses a threat has to be eliminated."
"Compared to morality or justice or whatever, one's own interests are more important."
"Isn't that right?"
"Having a boss like you is rather reassuring." Vermouth lifted her gaze toward Fujino after hearing his answer, quite satisfied with it.
When it came to practical matters, she greatly admired ruthless people who put themselves first.
Such ruthless people were often able to accomplish things.
Of course, someone like GUY little Shinichi
