I attended the first Orphan Black panel at Toronto ComiCon 2013, about a month before the show premiered. I remember walking into the room about 30 minutes before it started and getting a seat in the second row. I also remember wondering if I was wasting my time hearing about a show that might end up sucking. By the time it started, the room (rather small to begin with) was about a third full.
Turns out it didn’t suck. This year, I got to the Orphan Black panel about an hour early, and ended up sitting way back (which is why the pictures aren’t as nice). They did a raffle, handing out three hundred tickets (half red and half blue) half of which won free autographs (I won!). It turns out that a number of people in the back didn’t get the tickets, meaning there were more than 300 people in attendance.
