Who blew up Lassiters?

[LauBuch]

For me, the obvious choices are, the Quills, Dimato and his cronies, Jacka and John Doe. If it's one of them...then that "big surprise and shock" will just be a let down. But I'm not holding my breath, whenever they tell us we're in for a surprise, we're usually not.
Like the "hour long special" which was half an hour worth of footage we already seen.
