The original intention still stands. I didnt want to act on that information (or have Dark Matter obtain it) because I don't know how much of it, if any, had your approval. It's a bit meta, but it was either this or I'd be using information that isn't even true in the narrative. It just adds to the mess. Is rather take my chances and have Dark Matter attack the warehouse himself. At least he knew about it because he followed you when you went into the sewers. He didn't attack immediately because he wanted to ally with you, but than later discovered the titans gathered at their tower with new members. Anyone who reads the news likely knows Super Boy. Dark Matter was going to tell Jack this, but since he never responded to him, Dark Matter jumped the bomb and decided to destroy Jack himself. Using explosives to attract the Titans, if they care about random explosions in the city.
