why is kono not on the team right now?

because she stal money in season 1 and she had her badge taken away

she is not on the team cuz an other cop was using her to go under cover to catch this one guy!! she is back now thu

I bought all the season's and Kono had her badge taken away for the same reason Chin did. He was under investigation for taking money, he was cleared because he didn't take it. Their uncle did but Chin wouldn't tell on him so the Governor stated investigating Kono. She lost her badge & decided to go on the run with Adam Moshamorie (can't spell it) so now that Adam is gone & she found out he is still alive, she's going to try to find him because she fell in love with him.
That's why Steve hired Catherine Rollins (his girlfriend) to be a part of Five-0.
