It is incomprehensible to me that Kelly won't marry Brandon because they don't "swing from the chandeliers" and then immediately starts dating the supremely boring Matt.
Also, I love how Matt is initially kind of into Donna and then switches to Kelly. And it is incredibly simple to do. The "nice" girls are basically interchangeable at this point. Being "good" is their entire character- what horrifically lazy writing. Their various love interest use the EXACT same world to describe them- good, sweet, warm, caring, compassionate etc- BTW I am in fact making vomit noises. They're not even 2 separate characters at this point. Kelly could have just as easily been given the gang girl storyline.
