1989-90 was a bizarre time for EE, between Den & Angie leaving and The Mitchell brothers claiming Albert Square as their new stomping ground, there were a number of comedic storylines and characters that arrived who had all left by mid 1990. Did EE need the Mitchell brothers at that time? Did they save EE back then? And had they not arrived what could've happened or been changed? Aside from the obvious change in storylines I'm referring to the show itself.
