Jodie was basically trying to justify to Pete and Michael why she was ignoring them, she then went on to say she was upset when she got in the house because her dad was taken really ill and she started crying, Pete just said 'oh my god now you really are pushing for the sympathy vote, just 'cos your dad had high blood pressure and had to go for a check up' So Jodie cried even more. it was all a bit odd, Pete is so good at debating, he's got an answer for everything and he was tying Jodie in knots, she just made a fool out of herself. I'm not sure though how Pete knew Jodies Dad had just got high blood pressure, I'm thinking they were all in a 'holding area' together before they went into the house and Jodie had been told then, so they all act surprised when they enter the house.
