I used to have a life

So, I've been watching season two of Leverage and they just did one of my absolute pet peeves. :( The introduction of Tara. I hate when a show plays a character to be one thing and then, at the end, has them do a 180 on their personality because they were messing with the main characters. From good to evil or just naive lawyer to grifter, it really pisses me off to form an opinion on a character based off their initial impressions, only to find out it's all been a lie. Now, I don't mind when it's a gradual thing and the audience is in the know. Like a previously evil character turning to good (Spike on Buffy is an example) or visa versa over an arc is okay, but when it's a surprise? I hate it. And I like Leverage. Why did they have to do that? What I previously though was just a fun outsider's POV on the gang (I love those) turned into an audition for her on their team. We didn't even get fake!Tara meeting and being freaked out by crazy!Parker, which is what I really wanted out of the episode. And how come Tara never plays any more uptight lawyers? She always gets the sexy roles now, and I really preferred her the other way. Oh well. She's not too bad on the team and I think Sophie comes back soon anyway.
