Ep 1. Wiegel's Pregnant

In the season 4 premiere of Reno 911!, titled Wiegel's Pregnant, Deputy Wiegel drops a major bombshell on the department: she's pregnant. However, Wiegel refuses to reveal the identity of the father, sending her co-workers into a frenzy as they try to piece together who the mystery man could be.

As the Reno Sheriff's Department tries to solve Wiegel's case, they are introduced to a new Deputy, Frank Rizzo, who they quickly discover is a bit of a loose cannon. Rizzo's over-zealous approach to law enforcement puts him at odds with the rest of the team, causing chaos and confusion.

Meanwhile, Wiegel's pregnancy causes all sorts of problems for the department. She can't fit into her uniform, her morning sickness is wreaking havoc on her work, and her emotional state is all over the place. The team tries to be supportive, but their attempts to help only seem to make things worse.

To make matters worse, the team is faced with a number of seemingly unrelated cases, including a serial killer targeting prostitutes, a yoga instructor with a dark secret, and a pair of thieves on a crime spree. As they work to solve these cases, they are constantly interrupted by Wiegel's pregnancy-related issues, throwing them off their game.

Despite the chaos, the team slowly begins to piece together the identity of Wiegel's baby daddy. They narrow down the suspects to a handful of individuals, each with their own unique quirks and secrets. But just as they think they've cracked the case, a shocking twist sends them back to square one.

As the episode comes to a close, the team finally uncovers the truth about Wiegel's pregnancy, leading to a heartwarming moment of unity and camaraderie. And although the mystery is solved, the chaos of the day leaves the team wondering what kind of craziness they'll face in the days to come.
