What happened on last week's episode of "Scorpion?"

On "A Cyclone," "A bomb strike threatens the Internet infrastructure for the entire Southwest. Meanwhile, Team Scorpion fails a military training operation and becomes determined to prove themselves."

What should we look forward to for tonight's episode and the rest of the first season? Warning: spoilers ahead!

According to Carter Matt, "What is coming up next on "Scorpion"? "Shorthanded" is a title that suggests that this could be a true underdog story, and judging from the fact that the Scorpion team is trying in some ways to fight the law, it actually makes a little bit of sense. Just to make things a little more fun, we're also heading to Las Vegas! Who doesn't want to see some of these geniuses in a city so known for greed and insanity? We can only imagine some of the trouble that they could get into. Out of all of the episodes we've seen on the show so far, we're the most excited about this one in theory ... and we really hope that it lives up to some of the hype. After all, there are a number of little problems that we have with the story this week, and the show needs a little bit of bounce-back to keep people watching. This is still in that period of time where people could decide whether or not they actually want to keep watching moving forward, and there is some other competition out there on Mondays."

It will certainly be interesting to see all of this play out! Check out the "Shorthanded" trailer and preview videos here (promo clips contain spoilers):
