I don’t have a problem with HI taking "a break" (I don’t think it’ll return), but I have a huge issue with how there was zero communication about it. I know he doesn’t owe anyone anything, but come on… at least fucking tell us.
That was always how it was gonna end. Grey even mentioned it in an episode. Don’t remember which, but as soon as he said it I knew someday it would just end. With no reason, notice, or communication about it.
