Overview: Tragedy puts Erica and Dan's wedding at risk, with multiple traumas hitting the ED and Dan feeling responsible for the accident that brought them in. Dan feels helpless when a pre-wedding gag organised by his brother goes wrong and Dan finds himself tied to a tree while a horrific accident occurs right in front of him.
