So I watch this show called iZombie (it's on Netflix, highly recommend!!). In Season 3 Episode 9 they are investigating the murder of a Dungeon Master and question all of the players in his campaign. We met Steve earlier in the season and he reminds me so much of Snape (especially A Very Potter Musical's Snape) and then he gets this line!!
It should be noted Steve looks like this because he found out the girl he is crushing on likes Twilight and so he became heavily into Vampires, not because he's obsessed with Alan Rickman.
Are there any other shows where you've seen things that remind you of Harry Potter, intentional or not?
