For me I would imagine after Hiccup and Toothless became chefs / alfas toothless had a good day but Hiccups day was filled with stress from it seemed like 100s of problems ( most from the twins and Snotlout ) and even with 2 ice blocks him head was still in pain so when it was time to go to bed he just went over to Toothless and lad down with him and when Toothless let him knowing the day he's had Hiccup just said " Thanks bud " and then they both fall a sleep. What do you think ?
I can't stop laughing! Though Sherlock is like Toothless in many ways. Both rely on someone else (John/Hiccup) to do what they do best as John becomes Sherlock's moral compass and Toothless can't fly without Hiccup. Toothless and Sherlock sulk when Hiccup and John are slow or don't do what they should. Sherlock and Toothless both mimic their best friend regarding behaviour and facial expressions etc. Etc.!>>> pinning for the comment
