I did NOT think she was kidding/joking when she said --- in a PI, laughing, BTW --- that Jackie did "not know that you're on a date with me and my husband!"
The showing up unannounced on the group date last night? And, IIRC, that wasn't the FIRST TIME she's pulled a stunt like that (anybody please feel free to correct me if I'm wrong about that!). The "fall" down the steps --- just when Sean was about to take one of the girls on a date? --- then refusing to be taken to the hospital to be checked out? But feeling well enough to lounge/curl up on the sofa with Sean after all the shouting about your fall, and laugh?
We'll have to agree to disagree on this one.
And, regardless of whether or not it was Tierra, or, say, for an EXTREME example, Sarah (there is NO way I would ever believe that Sarah would, in this lifetime or any other, do some of these things, or say something like Tierra's latest off-the-wall PI statements!), to me, regardless of whether or not it was said in a PI (which to me is worse than saying it to their faces), or to their faces, Tierra making the statement that she wanted to "punch out these bitches" qualifies as mean.
And in light of her earlier statements/behavior/actions, Tierra COULD also qualify as totally to be taken as serious, crazy, obsessive and, yes, mean (at the VERY least).
Said it before: The girl needs professional help. She is NOT joking in anything she says OR does on this show.
