It was a good episode. It seems like they are finally giving Selina something to do. Galavan is using Silver as bait to lure Bruce into a trap, the question is who is going to save him? Alfred, Gordon or Selina? I'm thinking perhaps Selina because at the moment she's been warned off by Alfred but once she's saved Bruce, Alfred will probably be more receptive of her. When Bruce discovers Galavan's betrayal, that'll be another building block on the road to Batman.
You can see Penguin starting to turn against Galavan but I think his mother is going to end up getting tortured or killed when the Galavans realise what he is up to. They don't seem to be using Tabitha or Barbara a lot at the moment, Tabitha has been pointless from about episode 2 onwards. She's just a lackey whose position could be filled by any underling character.
So Fish Mooney came up with some characters thinking she's dead and others thinking she's going to come back. I think this could be foreshadowing her return, after all "no body no death" perhaps in a season 3.
Jerome has also been referenced again this episode, after last week's "ginger maniac" line, with Galavan's fake trauma about killing a man. I wonder if this could be leading up to Jerome's return somehow. He looked dead at the end of episode 3 but the references to him suggest that something is going to occur. Once is a coincidence, twice is suspicious. It'll be interesting if they make another reference to him next episode, if they do then something is almost definitely happening.
