[Death by Mirrors]

Ugh, let me see how many I can remember... Dick Grayson, Jason Todd, Tim Drake, Carrie Kelley, Stephanie Brown, Damian Wayne and Helena Wayne. I think Bruce Wayne himself once, but that's probably not what you're looking for. So I'll vote seven, even though I'm fairly certain I forgot at least one. That's your chance to step forward and fill in the blanks, guys!
