In the iCarly Season 3 finale, the episode centers around Marissa and Lewbert’s wedding. Carly takes charge of planning the perfect wedding for Freddie’s mom and is even given the role of maid of honor. Freddie appreciates Carly’s efforts and is touched by what she is doing for his family. However, as the wedding preparations progress, Carly gets caught up in the romantic wedding atmosphere and playfully mimics an actual ceremony with Freddie, which leads Freddie to believe she wants him to propose to her.
Freddie shares his plans with Spencer, Carly’s brother, who then informs Carly about Freddie’s intentions. Carly becomes anxious about Freddie interrupting things and Spencer mistakenly tells Freddie that Carly is not interested in marriage. This leads to confusion and tension between Carly and Freddie. Spencer, realizing his mistake, attempts to resolve the situation as he knows that Carly and Freddie are meant to be together.
Eventually, Carly and Freddie have a heart-to-heart conversation about their feelings and future. Carly opens up about her fear of marriage due to her own experiences with her mother’s failed marriage. She admits that the idea of marriage scares her, but she realizes she loves Freddie and wants to be honest with him about her feelings.
During Marissa and Lewbert’s wedding, an unexpected twist occurs when Marissa decides to elope with Lewbert in Las Vegas, leaving the wedding ceremony in confusion. At this moment, Millicent, another character, announces that she is ordained, and anyone who wants to get married can do so. Carly and Freddie look at each other and realize what they truly want. They recite vows they had earlier exchanged, expressing their love for each other.
As Carly and Freddie are about to say “I do” and fulfill fans’ hopes for a Creddie wedding, Carly and Spencer are taken aback when their long-absent mother suddenly appears at the event.
The episode ends on a cliffhanger, setting up anticipation for Season 4, where the consequences of their mother’s appearance will likely be explored.
