History
Arriving in the dystopia of Earth-TRN657, Beast went to work with his new tech to fix his time panel apparatus, only to discover the state of the X-Mansion that Banshee and the White Queen invited them into was in fact a Danger Room construct, before returning to their original timeline.[1]
