Caustic Lore Theories

I was looking up information on who the name just mentioned in the comics and it appears your first theory was just confirmed by a statement from Crypto... "Caustic: Do your worst, Ms. Paquette. You going to electrocute me again? I get to watch 203 people die. Why would I want a cure? Crypto: Because a new patient was just admitted ... her name is Katerina Ticacek, but she also goes by the name Mystik. That ring any bells... Doctor?" Which first off means Crypto knows Caustic's real identity most likely (I have not been too far in the caustic crypto lore so this may have been found out earlier but now its confirmed they know each other at the very least...) Im intrigued to know more lmk if you got anything else...!
