On Scorpion Season 4 Episode 16, it's Valentine's Day, and it's not going well for anyone on Team Scorpion. Paige has the flu, and Walter's attempts to check all the romance boxes are not going well.
Ralph gets his heart broken when Patty asks him to tutor the guy she wants to ask to the Sadie Hawkin's dance. To say that Ralph handles it poorly is an understatement. Instead of teaching the guy trigonometry, Ralph gives his awful tutoring lessons, ensuring that the guy will fail and not be able to attend the dance.
Oh, and Toby and Happy are waiting for their fertility results. The fact that their doctor hasn't called them back yet makes Happy panic that something is wrong with her, but after Toby hacks into the hospital database, he learns that his swimmers are the problem.
Don't worry though, Team Scorpion always looks out for each other, and they give Toby and Happy the money for fertility treatments.
Team Scorpion gets a case to save the doctor and pilot trapped in a helicopter that crashed into a skyscraper. The Santa Ana winds are making everything a lot more difficult.
To make matters worse, the trapped doctor is supposed to be saving the life of a patient in the ICU that doesn't have a lot of time. But have no fears, Team Scorpion is here to help!
Walter is able to take a dangerous zip line from the hospital roof to the building where the helicopter crashed. After managing to de-static the air, the doctor and pilot are able to get out of the helicopter safely, and they zip line back down to safety.
After they leave, the helicopter catches on fire and is moments away from exploding. Walter has to jump off the building, hoping that the strong Santa Ana winds will safely lift him to a lower floor and not let him fall to his death.
In the end, everything works out, but it would have been a lot easier if Walter could just apparate.
