Episode 3: 30 k run into AOD...only a dozen (let's be generous and say 100) run back...we see almost no dothraki fighting when the battle moves inside winterfell...D&D say, yes, they pretty much all died
Episode 4: now only half died
is that plain enough for you or you still wanna play stupid like that equation makes sense?
yea, i'll stand by this "nitpick", you go continue to defend other lapses in logic
maybe they can multiply bcuz there seems to be even more of them now in the season finale preview
