Wasted Characters *Spoilers*

I’m almost at the end of season 7 on my rewatch and I’m wondering about some characters who were introduced and either disappeared or had an untimely end.

Mike is one of them, he came in, did very little to help with the plot and then got killed off. Loved his Flamingo moment though.

Then there’s Officer Manzon who threw Deb under the bus to get a seat in the department and then disappeared.

Seems a waste of characters and screen time.
