The episode of "Chicago Fire" premiered on April 1, featuring the introduction of "Battalion Chief" Hopkins (Rob Morgan), who replaced Pascal (Dermot Mulroney) who was fired for his role in the investigation following Pascal's termination. Hopkins was brought in to oversee their house and five others, and Severide (Taylor Kinney) described him as "a real hardass". Hopkins also expressed concerns about Severide's tendency to work the same shift as his wife, which he claims has been approved by multiple chiefs. Despite this, Hopkins remains his superior and refuses to comment on personal issues with Severide.
