THIS SCENE GAVE ME GOOSEBUMPS
Seriously though, as soon as Alvin threatened to kill Astrid, Hiccup was prepared to actually murder him! We all know that Hiccup isn’t the type of guy who would take another persons life, but as soon as Alvin held Astrid over a cliff, he was ready to get his hands soiled with blood for her sake.
Even John Sanford quoted his determination saying that he was ready to do anything to get her back at that moment. Meaning, that the possibility of him actually murdering Alvin at that particular moment is extremely high.
Look at his face!: It goes from feeling helpless to murderous when he gives Toothless the command to kill Alvin with the Plasma Blast in order to rescue Astrid from her death.
IF THAT’S NOT LOVE I DON’T KNOW WHAT LOVE IS!
