I guess there is still one chapter left when josh tells him before he knows there will be ...

Accident?! (⊙…⊙ ) spoil me more （/TДT)/

I don't remember much i read it almost 2 years ago so only remember that peter gets into an accident with dog or something which chase is traumatized of so he saves peter and then josh tells him he's his child and this happens in the amusement park

thank you (づ￣ ³￣)づ
