What You Missed

If you still need to catch up to season 3, we’ve got some spoilers to help you along! Mid-way through season 2, fans said a sad goodbye to Megan O’Brien-Dodd (played by Camille Guaty). As it turned out, her Multiple Sclerosis (MS), which she struggled with since childhood, got the best of her and was her cause of death. The rest of Team Scorpion had a hard time saying their last words to her and many fans wept with her departure from the show. The much-loved character will surely be missed, departing in such a graceful and emotional way, but there are many more exciting moments for fans to see that involve the rest of the cast!

In the season 2 finale, episode 24 titled “Toby or not Toby,” Scorpion had to outwit the mentally-unstable, Mark Collins, who kidnapped Toby and threatened to torture and murder him, unless he received Walter’s Brain-Brain Interference research. The team was faced with a tough predicament, because if Mark got a hold of the information, he would have the ability to advance the technology to be able to read peoples’ minds. When the team finds Mark’s hidden location, Walter must make the tough call on whether to let his nemesis go in order to disarm his elaborate trap, or to capture his enemy and risk losing his friend. Meanwhile, Sylvester reveals Toby’s secret intentions, and Walter realizes his true feelings for Paige. All these dramatic events and more occurred in the season finale, so be sure to watch it before tonight’s new episode!
