Hi, first off I'm really new to this thing since my friends only introduced me to the whole CC stuff about a month ago, and I really want to meet Emily Kinney so I was thinking about going to this one. But, there is also the other London Comic Con going on a couple months before, and I'm just a student so I probably can't go to both with transport and other stuff, so is this one the biggest event, or is the this show event bigger?
