While trying to help out some stranded hikers on Episode 19 of "Scorpion", the team's helicopter starts to go down and eventually crashes.

The helicopter crash starts a huge wildfire that causes the team be endangered. They now need to figure out a way to get to safety.

The helicopter's pilot is injured and cannot get to higher ground. This means Sylvester must help rescue him.

Three clips have appeared online that give viewers a small preview of Monday's episode, according to On the Flix.

In the first clip, the helicopter crashes causing the giant wildfire. The Scorpion team is shown gathered together looking for a way to get away from the building flames.

In the next clip, Toby has put together a poster-sized chart on the reasons why Walter has feelings for Paige.

Toby says that the lavender fragrance that Walter has put into his office was because Paige likes the scent of lavender. Walter quickly said it was to mask the scent of mouse urine during experiments.

Toby says that Walter's excuse is disgusting, but "also a lie." He says that Walter knows that Paige always uses hand cream that smells like lavender and that is why he now has a lavender diffuser in his office.

Toby also says that he longer gets his coffee from the office because Walter has been putting cinnamon in the pot.

Walter says he does this because it has antioxidants in it and it improves brain function.

Toby adds that the reason Walter puts cinnamon in the coffee is because Paige likes it. He says Walter is giving her special treatment.

He then realizes "it can only mean..." before drawing a heart around two stick figures.

Toby clearly thinks that Walter has feelings for Paige. This causes Walter to start whispering.

"What is with the almost constantly commenting on me and Paige lately? It's borderline obsessive." Walter said.

"As a student of human behavior, I find emotional dishonesty offensive. And also, you're my find. Also I don't like Drew." Toby replies.

In the final clip, the team is looking for hikers in the helicopter with help of a laptop computer imaging system. The wind starts to pick up and the pilot looks like he is having problems.

This is when the pilot starts calling "Mayday" and the helicopter starts going down. The helicopter nears the ground and the clip ends. This is just seconds before the crash that ends up causing the massive wildfire.
