Dick met Kara's gaze and said quietly:
"He and Talia have a history. That's all I can say without keeping you up the entire night with the craziest stories about old guys coming back from the dead, a resurrection pit and ninjas. Ninjas." He could practically feel Bruce's anger about the situation threatening to strangle him if he said another word about Talia, so he remained silent, allowing Kara to make an observation that he himself had made a number of times while serving as ward to the Dark Knight. The impossible was never out of reach with him, though. Ever. 
"Charging into Lexcorp and demanding answers would be stupid, yes." Clark commented, rubbing his chin with his hand as he scanned the frozen image on screen for any discrepancies he could notice before shrugging. 
"I say that we do some more homework before we make any large moves. I don't know very much about the League of Shadows, but I do know Lex and if he's in bed with them, he's more than likely using them to subdue threats to his power, the docks being a small example of that. I can rummage around in my contacts, see if I can pull anything in street clothes. Worst case scenario involves me flying through the seedier areas of Metropolis and shaking down gang leaders for information. In any case, I can get info about Lex and the League's movements in Metropolis."
"I doubt BludHaven is going to provide anything of interest, so once I get Lavash thrown in jail, I'll do what I can to help. Haven't been to Metropolis in a while. Might be nice to not have to live in the shadow of creepy mansions and smoggy refineries." 
"The help would be appreciated." He turned to Kara, worry creasing his brow. 
"The League is something you don't have experience with, but telling you to stay out of this would just make you want to help even more, so  you and Dick find out what you can while I'm being Clark Kent the dutiful reporter." He then gave a look at Bruce:
"You know, Lex wouldn't turn down an opportunity to repair his image and one of your fundraising campaigns might be just the event to flush him out." Knowing that the Dark Knight probably had his own set of plans churning, Clark added:
"Unless you've got something else you'd like to share."
