What if those were ninja turtles and tried to kill the boy?

I think I'd react the same way

Because turtles are really cute.

is that a pigeon with a blowdart through it's head?

The turtles was the reason he was in this predicament; the unconscious boy was probably relieved his turtles were okay upon his awakening lol.

Because fuck Louis, that's why

Lewis would want the turtles to be alright....
