They leave things deliberately open ended and ambiguous so that 4 or 5 years down the line they can recycle the Becky/ Curtis storyline in some new "explosive" plot that is sure to "rock the cobbles". It will probably involve Betsy Boo falling head over heels in love with the spawn of Becky which resulted from a one night stand with some high profile drug dealer
I am already clinging to a lamp post waiting for my world to be "rocked".
