Notes:
– The Watcher’s dialogue is meant to be amibiguous regardless of whether the Prydwen has arrived. If it’s there, the words imply he’s simply waiting to be “picked up” or selected, whereas if it isn’t, they imply he’s waiting for the ship to arrive.
– While the encounter remains the same (mostly due to the limited protagonist dialogue options available) destroying the Prydwen will make the Watcher hostile due to the loss of his beloved spaceship
