In fact, the bad guys might have gotten away with the whole heist if Maddie hadn’t thought quickly and tipped Chimney off by dropping those three little words.
Her “I love you” was suspicious enough to Chimney that he brought in Buck and Athena, and they managed to eventually save the dispatchers and catch the thieves.
Maddie actually more than rose to the occasion in “The Taking of Dispatch 9-1-1,” and innocent dispatchers might have died if she (and a couple of her other brave coworkers) hadn’t taken action.
