When Hiccup and Marie found the island, Hiccup was so happy that he lifted Marie up and kissed her on the cheek.

Hiccup: Thank you! Uh...sorry about the kiss. *blushes*

Marie: No, no... It's okay. *blushes too* *giggles*

For the first time Marie finally found Love! For Marie gave Hiccup a Love Test...and it worked.

Hiccup: So this is where you found Toothia. *still amazed*

Marie: Yep. And it's beautiful too. Let me show you around.

Hiccup: Okay.

So Marie showed Hiccup around the island and found so many Night Furies. But for Toothless and Toothia...they were having a moment of their own.
