By season 7 episode 3, we have already seen that -
Daenerys has lost both her Westerosi allies - Tyrells and Martells
My question pertaining to this is-
Why hasn't Varys received any prior information from his little birds (or spies) regarding Lannisters plans?
In Euron's case, I agree the strategy would not have been discussed since it was his plan (and crew) all along but I believe the plan to take Highgarden should have been intercepted by one of Varys' spies. Being away from a place has never stopped Varys from gathering any information before. Why now?
