Hiiiiii! I am new to your reading list, but happy to meet you. I love Grimm, though am oddly non-fannish about it (I'm open to having my mind changed on that, I just haven't read any good Grimm fic), adore Criminal Minds, and have recently been introduced to Castle mostly through the TNT marathons during the weekday because I'm stuck on the couch due to hip surgery. I am a fannish butterfly with no stamina and it is a rare show indeed that will get me interested in a second season. Frankly, I'm shocked that I'm watching Grimm, but the second season is really hitting it's stride.
Nice to meet you!
