Better Call Saul, Season 4

[Jimmy and Kim visit Chuck's house the morning after his suicide by fire, and react to his death]

Jimmy:
So...?

Kim:
[holding back emotion] He says it started in the living room. Somehow one of the lanterns was knocked over, and then... [beat] The inspector says it was over fast. Smoke inhalation. So he didn't suffer.

Jimmy:
Yeah, they're gonna say that. Did you see the backyard? [Kim shakes her head] His microwave, his stereo, uh, the lights, dishwasher, all—all the kitchen stuff—everything electric is back there. The firemen didn't do that. He did that. [sighs] I saw him five days ago. He was listening to jazz, all the lights worked. He was himself. Something must have happened. Something made him relapse.
