(EPISODE 4 SPOILERS) Regarding ******** blood
I noticed that Riddler's blood in Episode 4 has been described to have a very similar effect to the Lazarus Pit from other Batman media. It heals physical wounds, but at the same time causes irreparable psychic damage and makes you go insane. Could this be Telltale's interpretation of Lazarus? This, in turn, actually adds some credibility to the "Avesta is Talia al Ghul" theory, because I have suspicion that even if Avesta really did destroy all the samples of Riddler's blood in The Agency's cold storage, she may have kept a vial or two for her own gains.
What are you thoughts?
