The 118 responds to a viral stunt gone haywire, a disaster at a couple's fishing trip and an epic first date fail. Meanwhile, Athena investigates a woman who doesn't remember being shot in the head and Eddie is forced to have a difficult conversation with Christopher.
Christopher mentioning to his classmates that tsunamis aren't a big deal is a callback to the events of "Sink or Swim" and "The Searchers" when he got briefly lost from Buck during the Santa Monica tsunami that swept through the pier.
Shay (Josh Duvendeck), Mitch (Amos Blackmon), and Jessie (Connor Trinneer, uncredited) previously appeared in the episode "Under Pressure", as mentioned by Buck when he says "Hey, why do I feel like I know this guy?", when they are tending to Jessie's injuries caused by the malfunctioning motorcycle.
