As Carter prepares for a camping trip with Henry and Fargo, Kevin's homework assignment - an emotionally intelligent robot called Emo - is kicking up trouble and spying on Jo in the shower. Andy arrives at Carter's house in response to a call, but as Andy seems to be mistaken, Sarah asks to check his circuits. Carter checks in on Allison, and offers to take Kevin on the trip so they can talk about the morning's Emo episode. Henry backs out of the trip, saying he wants to spend time with Grace, but encourages Carter to go for what he wants - a relationship with Allison. And Emo keeps bumping into trouble, making an unpredictable connection with Tiny.
As Henry helps Grace with a project, diodes strapped on his head, he can't hold back the truth any longer and tells her about the alternate timeline. Hurt, she walks out, and the diodes become malignant and hurt Henry. In another part of GD, a computer ignores Allison's directives and nearly kills Larry. As she, Zane and Jo investigate this, they discover a foreign program, and realize that Tiny, on her way to NASA, could also be affected and dangerous.
Grant manages to tag along on the camping trip, and though Carter bristles, he prefers that option to Grant spending the weekend with Allison. The guys find a spot and Fargo sets up a super high-tech tent, complete with video games and an AI system. Carter and Grant object, and all high-tech items, including cell phones, are tossed into a cooler. Carter tries to talk to Kevin about his Emo, and Kevin storms off.
As Jo puzzles out the robot mystery she realizes Sarah used Emo's emotional program to patch Andy so he would like her, and demands that she, with Zane's help, fix the problem. Jo rushes off to set up security to catch Tiny, who has escaped. Allison, unable to reach the guys, panics about Kevin's safety. Carter and Grant search for and finally find Kevin. Unfortunately, they also find Tiny, and she's on the hunt. They make a dash for the car and speed off - Tiny in hot pursuit. Carter calls Allison, who asks them to lead Tiny into their perimeter to be controlled. They almost make it to safety, but Tiny pins Kevin and aims her laser at him. At the last minute, Carter realizes that all Tiny wants is Emo, stashed in Kevin's backpack the whole time. It seems that the attachment patch had formed a strong, almost fatal, bond between the two robots. Her quarry secure, Tiny releases Kevin.
Zane finishes his cleanup with Eureka's robots, but Andy, newly in love with Sarah, begs to keep his patch - and Zane agrees. But love isn't as sweet for Grace and Henry, who are separating in the wake of Henry's news about time travel. Carter, having saved Kevin's life, makes his peace with Kevin, but Kevin surprises Carter by giving Cater his blessing on perusing a relationship with his mom. And Carter wastes no time in sharing the good news with Grant.
