What is the point of this twist?

I thought the scottish thing at the start was gonna tell katie's comments TO the housemates in her voice (they'd start to guess it was katie though) but her just saying it & no reactions is pointless & boring!

To isolate KT and cause drama

To give KH airtime so she can show the nation what a a hateful **** she is.

To isolate KT and cause drama
