Martha's hand was in Steve's pants when the fire alarm went off. Everyone in the office of Green & Associates leapt from their desks and bolted for the stairwells, but not Martha. She waited. She was the sort of woman who liked to let things simmer.

Based on Elena's knowledge ledger, she doesn't know about Marcus's secret as of Ch 8 — she learns it in Ch 10 when Old Tom reveals it at the market. The 3 scenes where this matters are: the confrontation (Ch 6), the tower escape (Ch 7), and the alliance meeting (Ch 8).
