I think that Edwina was pointing out the illogical nature of Kendra's "inspirational" arguments

- Kendra's point was that her decisions are made from her own perspective without taking anyone else into account
- Edwina's challenge was that no family or society can exist that way - you have to sometimes not put yourself first
- Kendra then lost the plot and started screaming at Edwina, swearing and telling her what to do
- however Edwina's sharp response focussed on was that Kendra's outburst conflicted with her own inspirational philosophy where no-one can tell anyone else what to do
However as Michael observed that contradiction in her moral philosophy was totally lost on Kendra - she lacks the ability to debate with someone with an opposing view - in her view she is always right/inspirational and its all tied up with psuedo philosophical/religious ideas

- interesting to hear Kendra call Edwina the devil
