New پرستار need help please

Well I don't really need ur help, I just wanna talk about something that has bothering me since the beiginning of S2

And that's how Jason completely changed 180 dgree from S1to S2 I mean in S1 he was like a business man with suits and short hair, he looked very official and all of sudden he has long hair he does gradding and stuff

I mean really? How can a person change 180 like that??
