Thanks for the new thread! I have read and understood the rules.
I was excited to see that video where Derek admitted he wasn't single. It was pretty cute: in my opinion, you could tell he was caught a little off guard, but wanted to be honest about it.
If they're dating, or even if they're just good friends, I hope Nina got to spend time with him after the Emmys, while he basks in the glow of his much deserved award.
Nina has been very quiet lately, so it's hard to know what she's gotten up to. If she has fallen for Derek, I hope she reveals more of that on Twitter.
Here's the video people have referenced before that really sold me on the belief that Nerek is real:
