With all the hype leading up to The Arrival you’d be forgiven for expecting something to actually happen. Would the cogs of the Reaper war machine rasp to life culminating in a bum-clenching cliffhanger? Would Shepherd finally cash in his chips in gallant forfeit? If not, what else could the ultimate sacrifice be? Would we witness a teary-eyed wave goodbye to a team member? Maybe we’d have to choose whom to bump off (sorry Zaeed). And who’s this Dr Kenson lady and why is she being held captive on the fringes of the galaxy? All good questions, the latter of which is first in line to be answered.
