Anyone else incredibly annoyed at how Harry left the show?

I get it, he did wrong by covering up for Dixon but his son got involved with some shady dude who was horrible and he was just trying to protect him. and Mark Driscoll was just horrible, the way he twisted everything and so proudly held it over Harry that he would complain to the superintendent about him - even though Mark was the one who got his son involved in the first place.

And Harry obviously couldn't let himself get blackmailed so he came clean - only to be fired and kicked out of the position. It made me so angry that Mark got Harry to leave like that and since we never see mark again after he threatens harry, I can only assume he continued to use his slimy demeanour to advance through school and life - he doesn't get any comeuppance in the show, which was very frustrating! I would have loved one scene after that where dixon confronts him and really lets him have it, for getting his father fired. but nope, nothing!

anyone else incredible annoyed by this storyline and wish they handled it better?
