Hiccup didn't return the village until afternoon to work on inventions to help Toothless fly.

Astrid walked down to the forge and says "I'm sorry, Hiccup."

Hiccup turns around to see Astrid and says "your never sorry for the shit you do! Don't talk to me ever again! We aren't husband and wife. Besides I tossed my wedding ring because I didn't want reminder of being your husband!"

Astrid grins "fine then! I never wanted to be your wife!"

In the morning, they arrive at Dragon Training.

Hiccup was prepared to face the dragon.

He hid an eel in his vest.

The teens got blasted.

Snotlout flirted with Astrid.

Astrid and Hiccup were the only two left.

Hiccup flashed the eel making the Gronckle runaway.

Astrid watched in shock that Hiccup chased after the Gronckle back into it's cage.

Gobber ask "okay. That was interesting."

Hiccup left to go try another idea to help Toothless fly again.

Next day, they faced the Deadly Nadder in a maze.

Hiccup learn scratching technique.

Astrid ran on top of walls to avoid falling and fell on top of Hiccup.

The twins came out.

Tuffnut comments "love on the battlefield."

Ruffnut comments "she can do better than useless."

Astrid swing the axe and shield into the Deadly Nadder making her whine in pain.

She turns around to see Hiccup standing up.

She scoffs "I can do better than Hiccup as far as lovers go" and walked over to Snotlout and kissed him on his lips.

Hiccup walked up to them and grabbed her by her hair and punched her unconscious and scowls "when she wakes up, tell her I said our marriage is over and she's useless wife! A slut!"

He leaves the arena and leaves two letters for his father and one for Astrid and his wedding ring on the stack of pictures.

He works on finishing the rig on Toothless and flew away to wherever.

Night time came when Astrid woke up in Gothi's hut.

Ingrid scowls "since you want to make out with your friend in anger. I'm ashamed to see you as my daughter! You ruined the Hofferson's name!"

Astrid ask "where's Hiccup?"

Ingrid answers "he left on a Night Fury after refilling the fish barrels he took.

Astrid ask "how long was I out? And did you say Hiccup rides a Night Fury?!"

Ingrid answers "yes. Now do you regret the shit you did to him?! He also left you a stack paper and journals of pictures with his wedding ring, annulment contract signed.

If you want to stay married, you have to rip it in front of him to cancel the divorce process."

(Elsewhere)

Hiccup and Toothless flew to Berserker tribe.

Dagur just finished organizing an armada of ships when Hiccup and Toothless landed on the lead ship.

Dagur laughs "well, if it isn't my brother, Hiccup."

Hiccup ask "do you want to help me end the dragon raids?"
