Bitty Schram leftMonkduring season 3, and the way the series handled Sharona’s exit arguably saved the show and made sure it would continue for five more seasons despite losing one of its best characters. Even though Sharona was only in three out of the eight seasons ofMonk, she remained an integral part of the show’s legacy. The fact thatSharona’s absence was felt duringMr. Monk’s Last Case: A Monk Movieshows how important the character is to the world ofMonk, which is why replacing her was such a difficult task.
Monk’s core cast of charactersdidn’t change much throughout the show. Apart from Natalie (Traylor Howard) replacing Sharona, the only other significant change in the cast ofMonkwas Dr. Héctor Elizondo’s Neven Bell replacing Stanley Kamel’s Dr. Kroger following Kamel’s passing in April 2008. While Schram would reprise her role as Sharona for a season 8 episode,Natalie became Monk’s assistant from season 3 onward.

Monk Didn’t Try To Create Another Sharona (& Gave Us Natalie Instead)
Natalie Was Nothing Like Sharona
Monkmade a conscious decision not to attempt to create a “new Sharona.” Firstly, the show chose not to recast Sharona, which itself was a great decision considering that Schram had already played the character for three seasons. However, Adrian would need a new assistant eventually, not to mention how Monk having a sidekick – his “Watson” – was essential for the character to work. This is whyMonkwould have to find a replacement for Sharona sooner or later.
Sharona returned in season 8, episode 10, “Mr. Monk and Sharona.”

However, simply trying to recreate Sharona with a different character would have been disastrous. Comparisons betweenMonk’s new assistant and Sharona were going to be inevitable no matter what, but having a “new Sharona” would have only made it worse. Fortunately,Natalie could not have been more different from her predecessor.The relationship between Adrian and Natalie was so different from how Sharona treated Monk that we quickly forgot one was supposed to be replacing the other. Natalie became her own character instead of a Sharona replacement.

Had Natalie’s character not been well-received, it’s difficult to imagine howMonkwould have run for five more seasons like it did. Not only did Natalie’s character work surprisingly well, but she also fit in with the rest of the characters very quickly. Only a few episodes after her introduction, it felt like Natalie had been there the whole time. Sharona’s exit was disappointing, butMonkfound the perfect replacement in Natalie.
