Marcus Hale

Broad, gray-faced building security officer who carries a sidearm. Has access to satellite feeds the other staff cannot see. Physically strong; able to carry the injured Hollis over his shoulders.

Acts without asking permission and moves directly to concrete action. Put the satellite footage on the big screen in Conference B on his own initiative. Under threat, he fires at the first alien, takes charge of the fire-door plan, personally slaps the releases, and checks Hollis's pulse. Takes the rearguard position when the group moves.

Terse and practical, favoring short commands ('Go. Go.'). Questions fiercely when confused or upset: 'Why him? I shot it.'
