I really really dislike the new character, Quinn. Why would she go from teaching the best of the best to being low(er) man on the totem pole, so to speak, just because Gibbs wants her to? Its illogical to me at best. She also just rubbed me the wrong way. I've always liked the actress, but she was so over the top for me, that it just didn't mesh for me.
I'll also comment here that I found it strange the deference that Gibbs gave her given she'd sent how many new agents that failed miserably and he kept getting them from her? And his putting his hand on her lower back to escort her somewhere within the office was probably meant to be 'gentlemanly' but I found it out of bounds for a workplace environment. They weren't on a date!
Anyway- I am not a fan, as you can see. Hopefully her character gets toned down a bit.
