yeah.. john wick definitely overreacted.. no dog is with a man's firstborn
even viggo was like "all this? it was just a fukking car and dog
"
then john wick replied with the ravings of a mad man so
at that point, it was obvious that john wick is just a lunatic who is grieving the death of his wife the only way he knows how. he has to kill someone or someones
and this psychopath has a certain set of skills
had viggo telling his son the john wick fable and shyt.. singing the boogeyman lullaby.. he knew his son would be sleeping soon enough
