HTTYD: Heather Report *There might be SPOILERS*

Tweet

I happen to stumble upon a blog about Hiccup's relationships in How to Train Your Dragon Animation. It was stated that Hiccup, in Heather Report episode, has "developed a crush on Heather". Is this true? I find it actually reasonable the first time I watched it but immediately dismissed the notion. If it's true, I honestly kinda don't like it. Not that I hate Heather but I just LOVE Astrid more than anyone next to Hiccup and Toothless. So, what are your opinions? Or what are your points to support this statement?
