She's a busy business lady. Meetings to make, feelings to fake, people to...partake? Shit to do. From my couple of playthroughs, it seemed she was more interested in fighting/poking at First to test their capabilities more than anything. Though, I'm sure if she were to get First alone there are far more better things than shopping on her mind.
...I should probably leave before my headcannon infests this board any further.
