[1] Kate Fields (Mamrie Hart) is a dentist assistant whose job is a bit middling, while her love life has resulted in either meeting people like Richard (Adam Lustick) on blind dates, or just staying at home alone most nights.
Old friends reunite, Kate talks with Dan and they hit it off, while avoiding Richard who has arrived in his goth alter-ego "Raven", and everyone is having a good time.
However, Oliver sees that Kinsey had arrived with her date Derrick (Leyva), leaving him a loner at the party despite occasionally bonding with her; and Charlie is having betting competitions with Peter (Chamberlain), which is against what she promised to Claire.
The three arrive at Ashley's home and throw toilet paper all over the yard, as they proclaim the best day and birthday ever, but Evie slips out that she hates her husband and wants a divorce.
Realizing it needs to be taken out otherwise the jaw will be affected, Kate puts the tooth out, and is overjoyed until police arrive and arrest the three, spending the night in jail.
It ends with the announcement of Charlie and Claire's engagement, and Kate's high school letter to herself now reflecting her relationship with Dan, loving her job, and the "child" in the form of Evie living with her.
