Don't jump to conclusions about that DxG kiss too quickly, guys. They may have had to kiss as part of a challenge like Duncan and Heather did in TDA. It may be a daydream that Gwen or Duncan is having. Or a nightmare that Courtney is having. xD

Point is, it's a preview designed to get you hyped about the season and to keep you guessing. I have to admit, though -- when I saw that kiss, I was disheartened, to say the least. >.> I only hope that this preview doesn't backfire and cause the thousands of DxC fans across the USA to stay away from the third season, lol.
