Stay away from the dog!

Okay, it has been almost two actual weeks since we saw pretty widow Ava's little boy, but I think the strips are delivered for coloring in batches, aren't they? So... is Andy's saliva acidic? Or merely bleachy? Or has the widow dyed her son's hair for some plot point? 'Cause surely it's not just carelessness! (And that's without getting into that bizarrely stilted dialog: "My son is becoming attached to your dog!" "Andy is a great friend... he has saved my life many times!" "My friends like you also!")
