Ever since Blake was adopted by Benny Severide, and became inseparable with Kelly, she always wanted to be a firefighter. Just like her brother. Recruited straight to Firehouse 51, and onto the same truck as Kelly, life was pretty good. Being the second in command to her brother, she went through the same hardships Kelly did, never leaving his side. Only Blake Severide's life gets a lot more hectic when Intelligence gets involved. Especially when she falls for the former Army Ranger.
