I'm certainly team Erica, but Ann's OK too.
Erica carried herself a bit differently than Ann, and seemed to be taken more seriously, Ann seems rather ineffectual at the moment in in (528) she just sits behind her desk looking exasperated most of the time... Erica also spent a lot of her time arguing with the department, Ann just seems to complain about them... nope, Erica all the way!
