Luke Cage Season 1: 13 Best Moments

After being shot in the previous episode, Luke manages to track down one of the doctors responsible for his powers in the first place, and with the help of Claire, convinces him to use his expertise to remove the engineered bullets lodged inside him.

The doctor uses an acid bath to diminish Luke's abilities, causing him intense pain to the point that Claire pulls him out of the bath prematurely. As the acid hasn't taken full effect, however, he has to be dipped in once again, which eventually makes his heart stop (but of course, he survives).

Again, this humanises Luke somewhat while giving a fairly coherent explanation for his condition and how it can be diminished.
