I couldn’t disagree more
I don’t for a second think Jamie believes her and Dave are a power couple. They can all easily see that Rhi & Jeff are the ‘power couple’ in the group.
I think she’s just happy she has a great guy who allows her to be herself. She doesn’t give any vibes at all that she thinks her and Dave are stronger than everyone else.
And she doesn’t give arrogance vibes either. She gives ‘girl with integrity, who stands by her opinion and lashes out when she’s hurt by the people she cares about’.
