what seems to be the officer, problem?
Slade needs to be a mainstay, he's too good of a villain to kill. Sending him to prison is the most logical choice since you can bring him back at some point.
I agree, he's my favourite in the show despite being a total simp. Manu Bennett has done a great job playing him. They could send him to prison if they cure him I guess. If they do, chances are it will be back to different villains each week like it was at the start.
