I watched this last night, and I didn't know if it was Liz or Julia. I was like, is she talking about herself in the third person or did she just slip?
This isn't necessarily mentioning Liz, this is more of her putting words into Austin because what Austin would have told them is that "He agrees with Clay and Audrey and that he isn't going to tell Liz," so really this video doesn't put her in a bad place at all
