General Hospital: Kristina...Seriously?

Ok I know she's a kid. She's confused. She's got serious daddy issues. Blah blah blah. She loses it when she years Sonny go off on Claudia after he found out she was responsible for having his son shot in the head. And then again today because an obviously spiteful and grief stricken Johnny says she had bruised from Sonny. She already knows Sonny didn't kill Claudia. So wth is she boohooing about! Yet she won't even hold Keifer accountable for beating the crap out of her?!! She wants to talk about how awful Sonny treated Claudia when she is the reason Claudia had a miscarriage. Grrrr! Am I the only totally fed up with her? Good grief! Also when the truth finally comes out will Kristina have to take any responsibility for her lies? Or will it be swept under the rug like her other lies?
