This is literally the most shocking scene in the show, even after someone spoiled it for me.

The fact that the actor also didn't know what was coming

the scene is shocking because it's unexpected also Saul and Kim's reaction was so realistic that you feel like they actually killed Howard's actor

Patrick Fabian?

yeah, Saul's actor is Bob Odenkirk, Kim's actress is Rhea Seehorn (not sure if I spelled it right) and Lalo's actor is Tony Dalton

i literally jumped off the couch after this scene.

I literally fell of my bed lmao that shit caught me off guard

I did too
