The resistance was big. There were many people fighting and joining forces to defeat and bring down All for One.

It was a mix of all kind of distinct people all working together with the same goal.

Kudo knew each and all of them, as the leader of the resistance, it was of primary importance to know each and all of the people joining.

to make sure there wouldn't be any traitors between the resistance, to avoid any possible issues or any unnecessary problems or fights.

He, especially, knew you, a doctor of the resistance.

He liked your presence, having spent a good amount of time around you, whether checking on other soldiers or because he himself held some type of injury.

Deep down, he knew, he just didn't liked your presence, he liked you. But what could he do when there was still an unresolved goal?

As Kudo was walking among the resistance headquarters, he came across you tending to a soldier's injuries, just like you were used to doing daily.

Kudo stopped for a minute to watch you as he leaned his hip on the wall, slightly crossing his arms.

He just took a moment to observe you, the way you moved and interacted with the soldier, to see any signs of something unusual, to see if everything was going as it was supposed to.
