Martina and Bruce Banner worked together in the same soda bottling factory; she would smile as he passed, though he feigned that he wasn't paying attention, as he was neither interested in her, nor did he want to get too close.
When a co-worker began to sexually harass Martina, Banner noticed her distress and asked her to lunch, hoping to help her. This angered the tough guy who began challenging Banner. When the Plant Manager approached and ordered the fight stopped, Banner grabbed Martina's arm and the two exited.
When General Thaddeus Ross and the Strategic Operations Command Center, including Emil Blonsky, came to Banner's apartment to capture him, Banner climbed through the window to Martina's apartment downstairs. She allowed him to hide for a moment, before he gave her a peck on the cheek and fled.
