They both consider Halloween their favourite holiday.
Both love Star Wars (including the prequels) but can't stand the fandom.
They both hate Liz O'Rourke.
Both plan to watch Carmilla, Dollhouse, and Firefly, and CC has been convinced to watch House of Cards and The Lying Game by Alex.
They both like to get into tv shows by marathoning or planning marathons - for instance, CC with Castle, Bones, Numb3rs, The Cleveland Show, The Mentalist, Burn Notice, Breaking Bad, LOST and about a million others or Alex with One Tree Hill, Buffy, Degrassi, Charmed, and others.
Alex is the third person CC has convinced to ship Bade. The first was Ari and the second was a friend of her's at school.
