I've re-watched a bit of the end of Series 9 recently, and one thing that struck me is how often the narrators and Lord Sugar reinforced how fair Francesca is. Did anyone else think that this was a bit odd? I didn't see any of that in the edit - she didn't strike me as outwardly unfair, but I didn't see why she was so particularly fair compared with all of the others. The only bit I can remember where this was obvious was when she didn't join in with the Rebecca-slating in Task 2.

Was this just brought up so much because they needed something good to say about her, perhaps? I fail to understand how she got as far as she did; I never saw her doing anything spectacular in any of the tasks.

maybe they wanted to show that LS held nothing against her even tho' she looked like Stella

My take on this is pretty much your conclusion. I think that because Francesca's path to Final Five was pretty lucky, they sort of made up positive things about her to justify her place there. To be honest, I agree that she didn't really deserve her place there. In addition, I wonder if this was meant to contrast Luisa's style. Fran was seen to dislike Luisa and be the anti-Luisa in many ways, so I wonder if this fairness thing was part of the show's storyline for her (Which was essentially her v Luisa).
