"Scorpion" season 2, episode 19 will see Team Scorpion helping out a girl who needs a heart transplant as soon as possible.
On Monday night's episode, Walter O' Brien (Elyes Gabel) and his friends will discover that a culprit has been tainting the blood supply that may otherwise be used for patients with serious illnesses.
The episode will also see the appearance of actor Horazio Sanz as attorney Heywood Morris, according to Cartermatt.
Meanwhile, the previous episode of "Scorpion" saw Sylvester Dodd (Ari Stidham) joining "The Price is Right."
In the past, Sylvester already expressed his desire to join a reality TV contest where he could put his math skills to good use.
However, his intention wasn't one that was selfish. Sylvester wanted to earn some money so he could have a wing at the hospital named after his late wife Megan O'Brien (Camille Guaty).
On the day of the competition, Sylvester surprised his fellow contenders, as well as host Drew Carey as to how he was able to give the closest estimates with every single answer.
At the end of the game, Sylvester was able to bring home $100,000, so his goal for Megan will actually come to life.
Elsewhere, Toby (Eddie Kaye Thomas) and Happy (Jadyn Wong) had a misunderstanding in "The Fast and the Nerdiest."
The episode saw Toby putting his gambling knowledge to good use when Team Scorpion was tasked to infiltrate a high-end car smuggling incident.
Although Toby was able to help the team, his girlfriend Happy realized how fearful she was of seeing Toby go back to that kind of life again.
While he was still gambling nonstop, Toby lost a huge sum of money, got into trouble, and was left all alone by his so-called friends.
At one point, Happy decided to confront Toby about his gambling addiction, saying that it's something that she will not tolerate.
Luckily, Toby told Happy that he doesn't have any plans to go back to that kind of life ever again.
He also gathered all of his gambling stubs, and burned them as a sign that he's choosing Happy over anyone else.
"Scorpion" season 2, episode 19 will air on CBS on Mar. 14 at 9 p.m. ET.
