Sissy is killing two birds with one stone! She can duck duck goose the 'cult' AND write about it for the paper! And just generally be uncomfortably fascinated with conspiracies and supernatural phenomena! So three birds with one stone!
Also, personally, I really love Tadhg have a sensible mind set (pulling a knife in school is bad!) but acting upon it in a very childish way (if I chase my sister around I can steal the knife and everything is better!)
I'll be at Anime NYC this weekend! Table J 11! I hope I'll see you there! : D
