Olivia did not know, and ultimately that was what made her decision for her. I’ll hold onto the armor until daylight, when I can assess my situation better. She might take one of two options then—leave the armor behind, and attempt to evade capture as long as possible as a fugitive—or use the armor itself as the bait that might attract her enemy to her. She could bank on Equestria tracking it to control where that final confrontation might occur.
