Exactly! Hanni does this (faux) posh thing were she tries to not move face when speaking. Michael's speech and body language is much more direct, if it was him it'd be more obvious.ps I'm certain it was Hanni who said "appalling artwork" - posh people are just like ventriloquists - they say things out of the corner of their mouths! Just try it out - you can easily say that without moving your lips much......
Cat certainly has the poshest accent at the chateau.
