Looking at the Timeline page, 3 days passed between Contents Under Pressure (the episode prior to this 1) and now, so it makes sense that Octavia had secretly been seeing Lincoln at his home, he could have spent some time training her to fight, and he may have taught her some knowledge/details about Grounder life seeing how she almost snuck up on him and had sex with him with no problem.
