If anything seemed beautiful t Astrid it was Hiccups and Toothless's friendship. They worked in sinc. Of course everyone had their own unique relationship with their dragons but Hiccups and Toothless's was so beautiful beautiful doesn't even describe it.
Most people thought Astrid's first ride was on Stormfly. They were wrong. It was Toothless that gave Astrid her first taste of open air. She owed Toothless a lot, Toothless seemed to understand that Astrid never really means to harm Hiccup so 9/10 times he leaves them alone. The great night fury was discovered to be the most human off all dragons and knew when Astrid needed a hand. In fact most of the time he encouraged Hiccup to make the first move.
It wasn't just relationship wise if it wasn't for Toothless Astrid probably wouldn't have a boyfriend. Oh yes if Astrid was thankful for anything Toothless gave her it was the reassurance that no matter how many stupid stunts Hiccup pulled Toothless would always be around to save him.
