This is just my opinion, I don't mean to offend anyone, I was bored so I made this. I just want to make it clear I like both couples so it's not like I'll say how bad one is and say how good the other is.

DxC: I shipped this couple so hard in TDI. GxT was okay, but I really loved DxC. They complimented each other well, they had so many cute moments. When I found out their was going to be a new season I was so happy! I couldn't wait to see more DxC moments. I was disappointed to see Courtney not there then I was happy again when she came back. I thought it would be worth the wait, but it wasn't. Duncan and Courtney came to have an unhealthy relationship. I still liked them, but I was disappointed at the way Courtney was acting. And that Duncan was willing to put up with it! I still thought they were cute. After a while though I stopped shipping them and I realized how many flaws their were. It's not that I would hate it if they got back together. It's just DxG has a healthy relationship. DxC getting back together wouldn't be for the best. I don't approve of the way they made Courtney turn out. She is now a paranoid controlling monster. Thanks writers -_- Courtney in TDA was just... a bitch. No other way to put it, she sucked. She had no interesting flaws. I don't know why but I still love her. I honestly can't say I hate Duncan. I just don't like him. He broke Courtney's heart, worked with Alejandro, and basically was a jerk to EVERYONE. He was likable in TDI, and cool in TDA, but now... God what a douche -_-

DxG: Okay. I ship this couple a lot right now. Fingers crossed they stay together! Unlike DxC, this couple is actually HEALTHY. They didn't start off very well though. Seriously, it's understandable if your tired of Courtney trying constantly to change you. I'm sure everyone understands how you felt, Duncan. But cheating is wrong! Even if you are better off with Gwen. Why not dump Courtney then later on start a relationship with Gwen? Oh, and don't get me started on how Gwen acted in all of this. I seriously lost 80% of my respect for her after all this. Gwen?! Hurting a friend?! I never thought I'd see the day. The writers made Duncan a jackass with no morals, and Gwen a weak-willed selfish idiot. I mean, she knew if she kissed Duncan, Courtney would hate her, and they were friends to boot. TDI Gwen wouldn't betray her friends, but TDWT Gwen is okay with it? Gwen already pissed me off a bit in TDI. I didn't like how the writers almost ALWAYS tried to make her look like the victim in every situation. They still do it too. Which I honestly think needs to stop. It's getting old -_-

I really like Courtney and Gwen still. I can't say the same for Duncan -_- Courtney is hard for me to dislike. No matter what she does. And Gwen is just a really likeable character. It's hard for me to dislike her too. Although it's easy for me to be mad at her and lose respect for her. Gwen pisses me off slightly. And I don't like Courtney when she's doing all her 'I'm calling my lawyer!' and 'we had a contract!' crap. All the other times I think she's just the best. I get why people hate Courtney. Mainly for the reasons why i dislike her sometimes. But also because she can act like something crawled up her ass and died. But that's just Courtney's nature.

Okay I'm done. Thanks for reading :)
