Supergirl, Season 3

Lena:
An employee of mine asked for help with a problem. And now that I've diagnosed the solution, they don't want to accept it.

James:
Sounds like they need an intervention.

Lena:
Tried that. It's not going well.

James:
Yeah, I had a roommate, in college. Great guy, but he started taking something. I'm not sure what it was, but he would come home, all hours of the night, and just tear the place apart. I tried to tell him that he had a problem, but he never wanted to hear it. So I just kept cleaning up after him.

Lena:
Did he ever acknowledge what was wrong with him?

James:
See, that's the thing. No matter how bad you want to help somebody, all you can really do is hold up a mirror.
