I'm just one person, so if the rest of the thread wants to RTB I won't stop that. Still, as only one person, I say:
Without the power armor. That stuff is bulky.
Spike, the DGs, Tosh, and the Aurors, all have tools that would allow them to find out if something's amiss. Spike's a detective, the DGs are made for paranormal investigating, Tosh is both a telepath and an espionage agent, and the Aurors can detect if a mind is altered.
Prio is finding out the nature of the damage to the Comms array, finding video feed of the anomaly, and comparing the base's comms staff's responses about needing auth codes to Transpace's S.O.P. for 'Base commander cannot into codes, need to use comms, what do'.
There's a good chance that the Comms array WAS damaged by The Event, that the Anomaly WAS just an Anomaly, the comm staff genuinely DON'T have any procedure for what happens if the Base Commander forgets his codes, and the investigation is a big waste of everyone's time and was just me jumping at shadows like a metagaming tard. Still, doesn't hurt to check.
