What might surprise a few is that Natalie seems to be trying to get Lydia voted out on Thursday. Right before the POV ceremony she caused a bit of a tiff between Russell and Lydia by reporting stuff back to Russell that Lydia was saying elsewhere.
Natalie also told Chima that she is 24 and has her bachelors degree - I can only think she picked this time to do that as a way to show she 'trusts' Chima.
In order for Ronnie to stay, he needs four votes. Who among these four will vote to evict Lydia? Kevin, Jeff, Jordan or Michele. I don't think any of them will. But Natalie is trying hard - she just told Russell it would be better to get out Lydia over Ronnie because Ronnie is not targeting him. He seems to not be buying it but Russell and Lydia have been butting heads.
