When his cousin Lt. Col. Roger Briggs returns from his own real space mission, he reveals that he faced the same bird-men Elwood warned him about, confirming that the dream was something far more than imagination. Their shared evidence suggests a genuine threat waiting in the cosmos, one that Briggs narrowly avoided thanks to Elwood's otherworldly warning.
