We haven’t heard mention of Wedge Antilles either. I’d like to see Wedge come back and help recruit new pilots or something.
They apparently offered Lawson a part in TFA - undoubtedly as one of the Resistance officers. He turned it down because he thought the part wasn’t big enough, which I find odd considering the size of his roles in the OT.
A larger part in IX - as Wook alludes to - something like he trains / or has been training up rookie/new pilots would be most welcome to see, especially if Poe is more of the Rebel Leader character in the next film.
