Claude is an utterly useless interviewer, he's intimidating but the majority of his criticisms make little to no sense under any scrutiny and are usually him trying to find holes where there are none, he's entertaining but I fail to see why any value is put into what he says. It wouldn't take much for someone made of the right steel (and I believe Luisa is) to silence or dumbfound him, as long as they have a good memory of and confidence in their figures (and I hope Luisa is, would be nice to see someone turn the tables on him, would make for good telly).
