You forget, though, Priya IS undoubtedly superior.
Funnily enough, the person in the house with the most inflated opinion of themselves could easily be Ryan. Or Travis. Or Lina.
I think you wrongly misinterpret Priya's self-belief, inner confidence and superb capability for verbal jousting as arrogance, when in fact she's probably the most empathetic and self-aware housemates left in the house. Priya is well aware of her own faults, her fault is she doesn't roll-over and take backchat lying down.
