Yes, getting a bit daft now! How many people do you know that go into their"local" in their pyjamas and confront the "big boss" of the Factory and accuse him of murder! It is getting more like "The Godfather! Tony will get into bed soon and find a clothes horse's head
No, if it was resolved any sooner than it ( hopefully for Maria's sake ) will be then that WOULD be unrealistic. There has not been any clear-cut evidence so far linking Tony with Liam's death now that Jed is in Wigan ( he isn't dead despite what people may think ) and Tony will produce him shortly to lend more credence to his claim that Maria is having a breakdown ( poor girl ).
