Scorpionâ€™s Valentine themed sixteenth episode, â€œLove Boat,â€ is sure to have a lot of rocky moments. It all starts with a car jacking. Some criminals steal high tech shoulder launch rockets that have a range nine times the standard and is near impossible to deter once on its course. The criminal, Christoph, is using a luxury cruise line as transport of the weapons. Homeland Security wants the man to whom Kristoff is selling the weapons, so itâ€™s time for the team to go undercover.
Toby finds a passenger who is supposed to board the cruise ship with his wife, valet, and trainer. The man is worth nine figures and yet somehow avoids the cameras since there has never been a picture of him posted. Sylvester is the only one who can get away with being 25 years old, so he poses as the passenger. Paige goes as his wife; Walter is the valet. And, Cabe is the trainer. Walter actually thinks heâ€™s joking when he suggests it. Although, who better than Cabe to be the trainer. Sylvester is terrified of the water and being on a boat, much to no oneâ€™s surprise, but Cabe and Walter assure him that they will be in and out before the boat even takes off. Who else thinks this isnâ€™t going to happen?
Walter and Cabe try to disarm the rockets and install the GPS devices in the cargo hull, but someone comes to check on the boat leaving them with no time to disarm the rockets before the boat leaves the dock. Meanwhile, Paige gets a call from Ralphâ€™s school. Heâ€™s feeling sick; the nurse said that he was shaking from chills. When Toby picks him up, he notices that Ralph faked being sick, again to no oneâ€™s surprise. Toby just smiles and takes Ralph with him.
Back on the boat, Sylvester is a mess when he realizes that the boat is taking off, while they are still on board. The captain comes to invite Sylvester and Paige, or should I say Mr. and Mrs. Chas Bonesteel, to dine with them at the captainâ€™s table. They oblige even though Sylvester is having trouble maintaining his cover as the mysterious Mr. Bonesteel. Down in the cargo hull, Cabe and Walter find the rockets and work to disarm them. They are interrupted by one of the criminals who gets away after Walter knocks him down. The captain orders all of the passengers to one area, where Christoph official takes over the boat.
Happy, Walter, and Cabe must think fast before Christoph and his men peg Sylvester and Paige as frauds. It doesnâ€™t seem to be fast enough when Christoph has a gun to Paigeâ€™s head demanding his rockets. Walter, speaking with him over the intercom, tells him that they will make a trade. Before handing over the rockets, Happy lets them know that there is a Japanese destroyer nearby. As they are making the trade, Christoph finds Walterâ€™s ear piece and hears that a Navy helo is approaching. He tells Cabe to give the all clear that it is okay to land and then launches a rocket.
With only moments until the impact with the Navy helo, Happy and Toby need to figure out a way to hack into the Japanese destroyer and stock the rocket. Toby says that they canâ€™t hack like Walter, but it just so happens that someone is there who can hack like Walter. Ralph uses the Japanese destroyer to fire a missile at the rocket to destroy it before it destroys the Navy helo. Now, before the Navy sends more help, the criminals want to get away. After it looks like the captain was helping Cabe and Walter, they finally realize whatâ€™s going on. Christoph is actually the captain who was the bad guy this entire time.
Walter convinces Christoph and company to take him as a hostage, saying that he is a high value asset. Sylvester finally gets the courage to not stand by, but to do something. He climbs through the ventilation system to get to the deck from where the criminals are escaping in a small boat. Without thinking about his fears, Sylvester jumps from the deck on the boat that is being lowered into the water. After a few nail biting moments, this distraction is just what the Scorpion team needed to save the day once again.
Everyone seems to be getting into the Valentineâ€™s spirit one way or another. Sylvester is sending a valentine to Megan, but heâ€™s trying to keep it a secret out of respect for Walter. Paige thinks itâ€™s sweet, and Walter even says any girl would be lucky to have a guy like Sylvester. Walter had a â€œbusiness dinnerâ€ lined up for him and Paige but ended up canceling it thinking heâ€™s doing her a favor by giving her a weekend off. Paige seems slightly disappointed by this news, but yet no one makes a move to fix that. Happy and Toby explore their relationship by taking the first steps toward dating, which for them includes holding hands. Happy did explain that Toby needs to be patient with her since sheâ€™s worried about ruining their friendship. Even Ralph gets into the spirit. He left school because someone else gave the girl he likes a Valentine before he got the chance. Toby and Happy help Ralph look great by setting off personalized fireworks at the school for the girl.
