Literary feature?

I really enjoyed the scene where Michael goes to the hospital to visit Vito. I think this scene stood out to me because of all the tension involved, knowing that men were on their way to murder the Don. Anyways, I was wondering about the part where Michael gets arrested by the corrupt officer before some Corleones show up.

The Corleones showing up gives the viewers sudden relief. I know that this is like "comic relief," but different because there is no comedy in this scene. I was wondering if this relief is a feature that should be noted.
