What's up with the obligatory "X are real?" remark in every episode?
This becomes most common in season 5, but there's a bit throughout the show.
Basically, every time the sisters encounter a new magical creature there is the need for one of them to say "Fairies/leprechauns/mermaids/genies/whatever are real?"
I know it's just a pet peeve but it annoys me. Like you've seen weirder than this, you're a witch, why act surprised? They finally got tired of it in the nymph episode when they said yeah we know about nymphs read it in the book.
