The small stories you wished they'd expanded on

Well this is a loose extension of the Leviathans; and one that Legendary Edition players will not get to see; but in the ME3MP the Awakened Collector character's description highly hints at the fact that the Leviathans are involved in the war in a more tangible way (kinda). 


The kit's description is that a Leviathan severed the connection of a Collector ship from Reaper control and that these former Protheans are now fighting for their dead race alongside the current cycle. This of course comes across as very suspect considering how the Awakened Collector doesn't vocalize or call out in pain when shot. It actually seems like its nothing more than a zombie; or more actually a meat puppet, considering what we know of the Leviathans and how they can control other species. Knowing that fact it seems far more likely that all the talk of 'Freed Protheans' is just war propaganda on behalf of the Citadel/Alliance government to cover up the fact that the Leviathan is just turning Reaper husks back onto their former masters. A lie to help bolster morale if you will.
