THE DAMN TRAIN DJ!
FTFY

the crossover have got to do with that, you haven't read the synopsis right?

Oliver has been learning to concentrate and patience with shado before, with slapping on the water.. Roy also has been undergone that training before when he was trying to control his strength.. so maybe just a deep relax mind can quickly trigger it

in the JL : Doom, batman's contingency plan for flash is strap a bomb around him and it can't come off, the bomb will explode if he drop his speed. But batman shows how to overcome that plan, flash has the ability to walk through walls because of his speed force, so he walk through an iceberg and left the bomb inside…

search on youtube "flash pulling a batman"

Yeah, it's a problem with arrow in almost each season, where the first half of season is still confusing and dont know where it leads, then Slade shows up!
I still haven't seen a threat from Ra's, what is the chances we will get another new series from Arrow? just like the flash. i think we need one more season to do…

yeah that smile and laugh, it's an honest "wow, that is cool bro"
