Sadly I don’t know of any, and I can’t think of any I learned about scrolling the tumblr tags. I wasn’t in the fandom when the show was airing, you see.
Hey, that’s okay! We’re so glad you found the show later on.
Feel free to check out our blog for gifs, meta, and liveblogs going all the way back to season 1’s original airing. Or! If you’d like to talk to some Grimm fans, you can join the Grimm Discord!
We’re currently doing a question of the day over there, too, albeit with slightly different questions. I’ll make today’s question the same, though, so you can hear some Grimm fandom lore from all us olds (I’m kidding…there are people of all ages on the Discord, though some channels are locked to 18 and over).
