FINN & RACHEL, SEASON TWO

Break Up, "Special Education": Rachel finds out that Finn slept with Santana, so she plans to sleep with Puck as revenge. She doesn't go through with it, but Rachel tells Finn what almost happened. He is heartbroken, and breaks up with her.

Back Together, "New York": While performing at Nationals, Finn and Rachel kiss onstage after singing an original song called "Pretending." They lose at Nationals, but at the end of the episode Finn and Rachel decide to give their relationship another shot.

"I swear,Noah! I''ll be okay!",the small brunette insisted. The mohawked teen sighed and finally nodded. He put his hand on her shoulder and guided her towards his truck that was outside.
She waved good-bye to her mother and other baby sister,then left with her brother whom to be was the boy with the mohawk.
"Rachel..." The petite female looked at the guy in the driver's seat and smiled.
"If any boy touches you-",he was interrupted by Rachel herself. "Noah...or Puck,it is not your place to keep me from other people. I''ll be just fine!"
They arrived shortly later to a small high school. Puck,being the good brother he is,opened Rachel's door for her. She nodded her head gratefully and gazed at her new school.
"Well Rach,welcome to McKinley High!" Rachel beamed and ran into it. Inside,it was overcrowded with students. Some guys whistled as she walked by,but immediately stopped when they caught Puck's eye.
"I''ll catch up with you later. Damned coach wants me at practice early. See ya." She watched him walk off before she entered her first class which was Spanish with Mr.Shuester.

They started like a lot of teen couples on TV shows do: he is cute and popular, she is far from being on the top of the food chain; plus, he is dating the head cheerleader who is much prettier than our young ingénue. That and some cute duets and great chemistry, created a fan base that would sit every week waiting for them to finally get together. I can understand that, they were downright adorable.
So season 2 came, and all the couple’s fans were probably wondering how this epic romance would play out, especially considering the characters contrasting personalities.
Personally, I think the outcome was a big disappointment.
While Finn seemed essentially the same, Rachel got double crazy. There were no more glimpses of the girl who gave her solo to Mercedes (S01E12), told the glee club “I realized being a star didn’t make me feel as special as being your friend” (S01E05), encouraged Quinn to go back to glee (S01E06) or had self-centered but funny tirades, like “I need applause to live”.
