Victor had just invited his old friend Dr. Jekyll to help deal with Lily after going on a huge bender of morphine and still not really being off the bender... He had told Henry about successfully bringing someone back from the dead and told him about Lily and they've made the decision to try and tame her instead of kill her

Victor: I haven't told anyone about what I have found except for one...

Jekyll: You told someone?? Why He says not really angry but just a little bit

Victor: Well it's not exactly my fault they just tend to appear unannounced He says struggling to explain it.
