The entire season she caused trouble for Gibbs, while trying to hit on him, but yet... did she have a purpose?
The last Episode Rule Fifty-One ends with him writing down a new rule about how sometimes we can be wrong, after she comes to him with evidence about him, saying something about how she won't do anything to him. This implies that he disliked her the entire time, but was wrong about it when she ended up not doing anything with the evidence she found.
To me, this character was not needed, and just an annoyance throughout the entire season, doing things that weren't legal, while at the same time preaching about legality to Gibbs, in everything he did.
My question is, is there any actual reason as to why this character was ever introduced? Does she have an affect in later seasons on Gibbs, possibly distrusting his gut on being "wrong," or was she there purely to annoy us?
