There's no point in her trying to be careful about recalling too much. Her language and speaking clearly demonstrate abnormal intelligence and experience-- everyone knows, so it's pointless trying to hide certain recollections. She shouldn't try to arbitrarily restrict herself, it won't be much of a surprise for others if she becomes even more capable.
Rather, she has an urgent matter at hand, and she practically only has a few years to collect all the information about it. Spending time beating around the bush won't really aid her much.
