Spoilers
Has anyone decided not to persuade the greenwalls with ironwood. If you were patient, it seems like margery will be able to help her with that and if asher pays a mercenary army then then there will be a clash of armies with rodricks. On the other hand even if the Forresters give all their ironwood, it seems likely they will still have a supply of ironwood in the north grove.
With the death of joffery coming up, it seems likely that mira will be unable to help the forresters much. Then again if Asher fails to get an army that could also be bad. Asher will likely have to swear forrester loyalty to daenerys or give up some of the forest. Causing a rift with the lannisters and Rodrick.. Also he could go back an marry gwyn whitehill. The next episode should be very interesting.
