Bum Gyun doubts

I was wondering what happened to the Kim Min Ji case, they totally neglected it and the distantly we got into the case again lol and it was obviously only for Bum Gyun doubts. So that we get a reason why he changed his mind and now thinks human b is a good? choice but then in the almost same scene Ho Soo who also changed his mind out of blue comes and changes Bum Gyuns mind again lol. That was fast. But I'm happy that Ho Soo is finally with the team and I still doubt that Woo Jin is the chairman. But if he is then I think he has been manipulated somehow.
