"Scorpion" season 2, episode 21 will see Walter (Elyes Gabel) potentially admitting that he's jealous of Scott Porter's character Tim Armstrong.
In the previous episode, Tim was introduced to Team Scorpion, and was tasked to work with them. At first, Walter didn't seem to mind that he had to work with Tim, but he obviously felt off when he realized that Tim may be interested in getting to know Paige (Katharine McPhee) better.
Meanwhile, the teaser released by CBS for episode 21 also showed Walter feeling jealous and pissed over the fact that Tim is better than him at one game.
The sneak peek showed Sylvester (Ari Stidham) gushing over how great Tim is in the game.
"Holy smokes! You beat off the colonel clones, you made it to the galaxy and you sold all of your lives. Can't you see how incredible this is?" Sylvester told Toby (Eddie Kaye Thomas) and Tim.
"I just used to play this game when I was a kid," Tim said humbly.
"Actually, the Neuro transmission speed between the brain and your fingertips is pretty amazing," Toby answered.
At this point, Sylvester asked Paige's son Ralph to watch the game.
"Ralph, you gotta see this!" Sylvester said.
However, since Ralph was busy watching something on his iPad, he wasn't able to hear Sylvester.
"Ralph, you're missing out!" Sylvester said.
"What is all the ruckus?" Walter asked his teammates.
"History being made!" Sylvester replied.
"He's about to beat your high score!" Toby told Walter.
"Well, that is nearly impossible. I memorized the graphic patterns..." Walter said.
Toby then said that Tim is obviously beating Walter's high score already, but it's obvious that the latter didn't want to believe him.
"Well very good, but physical advantage will eventually win in the face of superior intellect," Walter said.
"Walter, are you threatened by this?" Paige asked him.
"No! It's a videogame. A videogame for which I possess the high score," Walter replied.
"For now..." Toby said sarcastically.
"You seem threatened," Paige added.
"No, I'm not. I'm hungry. Are there any egg bagels left? Walter said.
"Scorpion" season 2, episode 21 will air on March 28 at 9 p.m. ET on CBS.
