After their conversation online, everything got better. They still weren't speaking to each other in public, but they nodded and smiled at each other, which was a major improvement. Even the Glee Club atmosphere cleared up. Things were almost like before. ALMOST. Tina and Artie were never partnered together, after the incident that happened last time.
The tension that seemed to surround them seemed to have dissolved. It was a miraculous sight. After all that they went through, they eventually became friends again. As for the romance, it was decided that Mike, Tina, and Artie were better off as best friends. Now 10 years later, they are inseparable. Life throws curveballs at you, but it's better to embrace it than avoid it, as the trio has learned. As for Sunny, well it can be of no surprise when she was arrested for the murder of Sue Sylvester, what with her disregard for authority, and Sue Sylvester being the power hungry woman she is.
I know it's a crappy ending. Sorry. I can't think of anything else to conclude it. I'm getting tired of writing this story. I don't hate Sue Sylvester, I just think that she and Sunny wouldn't get along, and with her mood swings, it could happen. Don't hate me!
