Eureka: Season 3, Episode 9

3 - 9: Welcome Back Carter

Following Carter's dismissal, Fargo and General Mansfield decide to field-test a new robotic sheriff named Andy. However, the unfortunate robot seems to be the target of random gravitational anomalies which repeatedly crush him, and Carter cannot help but get involved. When Andy refuses to help due to low chances of success, Carter volunteers and gets close but fails. However, Andy, inspired by Carter's bravery disregards the odds and saves him. Working together they save the day, doing a job that neither of them could have succeeded in alone. Afterward, Andy realizes that Eureka is better off in Carter's hands and exploits a loophole in the town charter to have him reinstated stating that after calculating the odds, he believes Eureka has the best odds of survival with Carter as sheriff. At the end of the episode an alien object is detected heading straight for the town.
