There were two reasons Eli acted like a jerk in front of the media...one was to challenge the person to come after while the other one was.....to find out who targeting his 'future daughter'.
Yes, when he killed the media members in the DC News, Eli checked their data before destroying everything....he wasn't that much of an idiot.
And he found interesting things along with corrupted nobles' dark side...it was to kidnap the Zera Adriana, daughter of Vampire Queen.
Eli was shocked to see so many nobles corrupted to their core as they literally illicitly trafficked the demi-humans, Atlantis, and children. However, he was more shocked to see that they planned to kidnap Zera while diverting Adriana.
Although 'that Newbie' did babble, without strong evidence Eli or even Adriana would not be able to make a move.
So he didn't say anything to her as the data only has a one-sided discussion it never mentioned Dracula or any other noble family.
