The only person who told Priya the truth.
Priya is going to watch this series back and realise Julia was the only person in that villa actually telling her the truth.
Everyone else nodded along and told her what she wanted to hear (or worse manipulated her for their gain). Julia said the uncomfortable thing to her face, stood by it when it got replayed in front of the whole group, and then the next clip proved her right.
That’s not meddling. That was her best ally in there purely for being honest. When Lorenzo stood by Julia’s opinion in tonight’s show she accepted some of it (given the delivery) from Lorenzo and acted on it. She will see that she was never part of the Jasmine and Mika click and that they weren’t “her girls”.
