I assumed the scene in Dorne takes place farther in time than the scene of Dany sailing to Westeros. I'm just confused that we saw Varys leave for Westeros a few episodes back, and he's there on the ship with them though
lord have mercy.... he left mareen to find allies in westeros...
he got there and found the sand snakes who hated the lannisters... the lannisters being who killed dany's family
while there, the cersei shyt happened... so he called mama tyrell because she'd want revenge on them for killing her son and grandbabies... in comes vary's like "well i got this dragon queen coming with an army.... dorne is the only one to not lose to the dragons so lets click up.... and the tyrells have the largest army still, so lets click that up too"
now he has the biggest army in westeros along with another army of people who were the only ones who could hold off dany
add that to the greyjoy fleet and men... the slavers fleet and men... the dothraki 100k... the 8k unsullied... and 3 dragons
vary's figured that's enough fukking people.... so he rides back to tell dany it's time to move out...
then they all float back to westeros
you're going to ask why he didn't just send a message.... cause he has no more little birds... and a raven is not flying across the damn sea
